英文摘要
This research aimed to develop ultimate spin oscillators and detectors with high Q-values and high efficiency. To realize the purpose, nano-scaled spin-superstructures including ferromagnetic nano-dot arrays were fabricated. The influence of the ac spin current injection on spin torque oscillation has been also investigated within the framework of macro-spin model. Moreover, oscillation spectra were measured for actual nano-scaled GMR devices with large magnetoresistance to develop novel oscillation devices.
