Spin Hall angle and spin diffusion length of permalloy
Source abstract
Abstract
The inverse spin Hall effect (ISHE) in a ferromagnetic material (FM) has been attracting much attention due to its importance in spintronic applications. ISHE, which converts a spin current into a charge current, is an effective method for detecting spin currents. In this work, we report the observation of ISHE on permalloy (Py) thin films under the ferromagnetic resonance condition. The values of the spin Hall angle (θSHE) and the spin diffusion length (λPy) for Py are determined to be 0.034% and 7.0 nm, respectively. The values of θSHE and λPy are investigated for the first time with spin pumping techniques for a FM.
