Abstract :
We have developed a high-frequency ESR technique using a cantilever. In this method, magnetization change caused by ESR absorption is detected as cantilever deflection. In this study, spin sensitivity as high as 109 spins/Gauss was achieved at 80 GHz by an optical modulation method. We also succeeded in angle-dependent ESR measurement at 80 GHz using a cantilever.
