Abstract

Microwave induced spin-Hall effect has been investigated in sputtered Co/Pt bilayer thin film for its application in the field of spintronics. Measurements were carried out in the frequency range from 0.1 to 10.0 GHz at 10 mW power level with a sweeping magnetic field up to 0.2 T. The maximum dc voltage measured was 5.78 mu V at 0.1 GHz in perpendicular applied magnetic field on the bilayer film. The direction of magnetic field, frequency, and power level influence the ferromagnetic resonance signal. Measurements confirm lower effective spin pumping due to a weak perpendicular anisotropy in the film.
