Outline of Final Research Achievements |
In this study, we focused on the coherence of spin currents to realize ultra-sensitive devices using spin currents. In order to clarify the quality of the spin injection process in nonlocal spin valve devices, we established a method to quantitatively evaluate the conduction process in junctions consisting of ferromagnetic/nonmagnetic materials by means of shot noise measurements. We also developed a method using circularly polarized microwaves as a new element for generating and controlling spin currents. As a result, we have realized polarity-resolved control of magnetic dynamics using left and right circularly polarized modes. Here, we have developed two different methods using cavity resonators and crossed microstrip lines, which provide precise and broadband control of electron spins, respectively.
