Abstract

Angular-dependent magneto-optical Kerr effect (MOKE) and coplanar waveguide ferromagnetic resonance (CPW-FMR) measurements were performed to unravel the nature of anisotropy present in Ni\(_{80}\)Fe\(_{20}\) (Py) thin film. The “in-plane” angular variation of coercive field (\(H^{IP}_{c}\)) and resonance field (\(H^{IP}_{r}\)) confirms the magnetic anisotropy is negligible, where the spins are confined to the plane of the Py film. The variation of resonance field in “out-of-plane” geometry, \(H^{OP}_{r}\), strongly indicates the presence of “out-of-plane” uniaxial anisotropy in the Py thin film. Also, the inverse spin Hall effect (ISHE) technique is employed to measure spin pumping-induced DC voltage, V\(_{ISHE}\), generated across the Py/Pt bilayer. The line shape analysis method has been utilized to distinguish ISHE and spin rectification contributions. The measured V\(_{ISHE}\) at low (4 GHz) and high (35 GHz) frequencies confirm the pure spin current injected through the Py-Pt interface due to spin pumping using CPW-FMR setup, which has a direct bearing on the realization of quantum metrology through the spin current quantity.
