In NiFe/Pt bilayer, when spin current originating from the magnetization procession of Ni Fe is inject into the adjacent Pt layer under ferromagnetic resonance(FMR), the direct current(DC) voltage VISHEgenerated by inverse spin Hall effect(ISHE) will be added to the voltage V_(SRE) generated by spin rectification effect(SRE), therefore the measured voltage in experiment is the sum of VISHEand V_(SRE) . It is crucial to separate these contributions, which has been often overlooked before, in order to make a ...
