文摘
- •
Hysteretic behavior of ferromagnetic resonance spectra in the CoFeB/Pt sample.
- •
Hysteretic behavior of inverse-spin Hall effect voltage in the CoFeB/Pt sample.
- •
Proportion of inverse spin-Hall effect voltage can be determined by the cavity mode.
- •
The hysteretic behavior arise from the unsaturated magnetization limit.
- •
The well-defined spin Hall angle which consider a hysteresis can be obtained.
