  Based on the high-resolution magneto-optical microscope developed before the start of this research, we have constructed a time-resolved magneto-optical microscope using a pulsed semiconductor laser as an illumination source. Compared to conventional time-resolved magneto-optical microscopes, the new system has not only higher resolution but also enables simultaneous measurement of the three components of the magnetization vector, and is more stable and flexible in measurement. We have succeeded in applying a high-frequency magnetic field of several tens of MHz to a permalloy thin-film rectangular structure of several micrometers per side, and observed the gyration of magnetic vortex using the above apparatus. The use of a semiconductor laser light source made it possible to measure the excitation frequency dependence of the magnetic domain dynamics and to observe the resonance of the swirling motion of the magnetic vortex.

  We proposed a "microwave chemistry chip" in which a microchannel is inserted into a microwave (24.15 GHz) post-wall waveguide to heat and react. By making the applicator irradiated with microwaves (24.15GHz) as a resonator type that generated a standing group, we succeeded in rapidly heating water to 100 ° C in 5 seconds (microwave input is 4W). In addition, by using a method that combines synchrotron radiation lithography and prototyping, the chip fabrication error was suppressed to ± 5 microns or less, and the heating uniformity was greatly improved. As an application to the reaction, we succeeded in the production of gold and silver nanoparticles and monitoring the synthesis of ruthenium complex as a two-dimensional distribution of fluorescence emission in the flow path. As an application of the multi-step reaction, we took up the coupling reactions and started to design a prototype chip in which chemical operations correspond to it.

  In order to quantitatively control what kind of information is transmitted inside and outside the cell, we conducted research and development on the elements and mechanisms necessary for an integrated nanomicrosystem that provides an ideal experimental environment. We have succeeded to some extent in creating the mechanism as expected. First, it was shown that a microchannel system can be constructed by microfabrication of PTFE and PMMA, which are structures, with high aspect ratio and high accuracy. In addition, we were able to propose and implement a method for rapidly performing laminar flow mixing and quantitatively evaluating changes in the degree of mixing over time. We have also succeeded in bioimaging by surface-enhanced Raman scattering and increasing the sensitivity of magnetic centers using nanomagnetic materials, and also succeeded in molecular imaging of biological models.

  To establish micromanipulation technology of dry powder particles using surface acoustic wave (SAW), we examined about the transport of insulation powders that had not been transported by a SAW actuator. It was found that the insulation powders could be transported by inclining the SAW actuator, i.e., by using the force of gravity. Then, in consideration of practical use, we fabricated and investigated a miniature feeder by a mounting hopper on the inclined SAW actuator. We succeeded in feeding several mg of the insulation powders by the SAW feeder. Moreover, we surveyed about application of the SAW actuator. It was found that the SAW actuator could be used in the field of electrochemical analysis because of its ability both to stir and warm liquid.

From this point of view, we investigated the information and power transmission technology through spin wave transmission without charge current. We focused on that the magnetic moments tightly coupled with their lattice within a crystal. We studied the magnetization dynamics by combining the spintronic approach which controlled the magnetization through the strong shape anisotropy with technology associated with surface acoustic wave excitation and transmission accompanied by lattice oscillation. We qualitatively understood the magnetization dynamics induced by the current, magnetic fields, and temperature rising due to the Joule heating excited by SAW and current by comparison of the theoretical approach, simulation, and experimental results within the microscale artificial magnets.

  Recently in the electronics and drug industries, physical operations such as the transportation and separation of micro dry powders are required. However, it is impossible to operate the powders with accuracy by miniaturizing a general-purpose conveyor or blower. Therefore, we focused on a surface acoustic wave (SAW) device whose structure is simply, and investigated powder transport properties by the SAW device. As a result, it was shown that powder transport direction can be controlled by changing a drive frequency applied to an interdigital transducer (IDT) that generates the SAW, and its powder transport efficiency becomes higher as the IDT's pitch size increases. Moreover, it was also shown that the powder transport speed can be suppressed by thickness of a metal film formed on the SAW propagating area. On the base of the obtained knowledge, we succeeded in fabricating a high efficiency transport feeder for dry micro powder.

  Magnetization reversal, that has been investigated through the ages, is crucial important for both fundamental magnetism and engineering applications. Recently, on the technological application of new spintronic devices, microscale and nanoscale ferromagnets have proven to be appropriate for clarifying the spintronics associated with magnetization dynamics induced by spin-polarized current and voltage. However, the Joule heating and high current density required for the magnetization reversal are problems for device applications. In this study, we focused on that the magnetic moments tightly coupled with their lattice within a crystal. We investigated that the magnetization dynamics induced by the surface acoustic wave (SAW), spin-polarized current, and microwave magnetic fields. By comparison of theoretical approach, micromagnetic calculations and experimental results, we qualitatively understood the magnetization dynamics induced by the current, magnetic fields, and temperature.

  A three-dimensional magnetic recording in a multi-layered stacked magnetic pillar was investigated using micromagnetic simulation. Selective magnetization switching is possible with the assistance of a circularly polarized microwave field with an adequate corresponding frequency. The value of the saturation magnetization of the magnetic layers is critical in suppressing selective magnetization switching errors caused by magnetostatic fields. A large saturation magnetization of up to 600 emu/cm3 in the second layer allows successful three-dimensional magnetic recording. Microwave-assisted recording on a 500-Gbpsi-class perpendicular medium was experimentally demonstrated at room temperature. A frequency-dependent reduction in the switching field was clearly observed in response to a microwave impulse 50 ns in duration. A significant reduction of up to 30% in the coercive field was achieved by applying a microwave impulse with an amplitude of 25 dBm and a frequency of 15 GHz.

  We established noise reduction technology for a micro magnetic sensor(magneto-impedance sensor) utilizing spin dynamics in case of pulse current excitation. It is shown that noise level of the magneto-impedance senor is smaller than 1pT/Hz^<1/2> at room temperature. It is investigated that resonance frequency of magnetic wall with rotating magnetic vortices is controlled by spin transfer torque. It is shown that resonance frequency of the rotating vortices sensitive depends on applied magnetic fields.

  The transport phenomena and spin-diode effect of a single layered ferromagnetic Fe_<19>Ni_<18> nano-wires and nano-disks in a radio-frequency (RF) frequency region are investigated. The microwave rectifying effect in single layered ferromagnetic wires is induced by the anisotropic magnetoresistance oscillation due to the magnetization dynamics in the wires. This rectifying effect provides sensitive detection for the magnetization dynamics in nano- or micron scale magnets.

  This study is on the spin-topology and quantum magnetics in nano-structured magnets. The results of the present study are summarized as follows ; 1)By using a new domain wall resonance spectroscopy, the mass of a magnetic wall in a semi-circle nano-line is determined to be 6.6x10-23 kg, the value of which is well in agreement with that predicted by V. W. Doring in 1948. It is shown that the domain wall is driven by low AC current density which enables negligible small Joule heating. 2)The magnetic structure and magnetization process in a Permalloy wire-based honeycomb network have been investigated by means of MFM and magnetoresistance. It is found that the magnetic structure is governed by magnetic interaction similar to the ice rule. By decreasing the exchange energy at the vertices of the network, the ice-rule type of interaction causes a transition of the magnetization process. 3)Magnetoresistance for tri-layered Py/Cu/Py nanoring is measured. The ring detects the electron coherence modulated by the inhomogeneous magnetization distribution. 4)The magnetoresistance effect and the current-voltage characteristics in ballistic nano-contacts in the regime of conductance quantization are investigated. The spin arrangement in the contacts plays an important role for quantum conductance. 5)The inverse process of the spin-Hall effect is observed at room temperature in a Py/Pt thin film by the ferromagnetic resonance of Py film. 6)The conduction of a single ferromagnetic nanowire in a radio frequency range is investigated and the magnetic field and frequency dependences of the spin torque diode effect are clarified.
