Research Abstract

Scanning microwave probe, which can inject spin locally and apply spin torque to the magnet, has developed. Very thin high-frequency coaxial cable was used as the microwave source and detector of up to 10 GHz, and local excitation and detection of spin transfer torque oscillation was studied on the magnetic tunnel junction layers by injecting spin from the probe.
