Outline of Final Research Achievements

Based on new concepts in “Spintronics,” new magnetic devices for RF applications have been developed. As a result, it is clarified that a current injection to an about 100 nm size magnet results in an RF auto-oscillation up to 100 GHz, and electric connection among them causes synchronization and a high RF output like 100 micro-watt. In addition, we successfully applied an STO for a phase-locked-loop (PLL) and obtained an undetectably narrow linewidth of auto-oscillation. It has been also shown that the device can be a highly sensitive magnetic field and magnetic resonance sensor. The device also shows RF rectification functions with three times better sensitivity as compared to semiconductor diode detectors. The devices are expected to find practical applications in high frequency electronics.
