Abstract
In this study, the output DC electric voltage (Vout) generated by a Pt-capped Fe4N bilayer film (Fe4N/Pt) under ferromagnetic resonance conditions at room temperature was assessed. The contributions from the inverse spin-Hall effect (ISHE), the planar-Hall effect (PHE) and the anomalous-Hall effect (AHE) were separated from the output voltage by analysis of Vout values determined at varying external field polar angles. The results showed that the polarity of the ISHE (VISHE) component of Vout was opposite to that of the PHE (VPHE). As a result, the magnitude of the intrinsic VISHE was beyond Vout by as much as the magnitude of VPHE. The X-ray diffraction structural analysis revealed the polycrystal of the Fe4N/Pt with (001) orientation, which might be one of the possible mechanisms for enhanced intrinsic VISHE.
