| Abstract: | The magnetic spin Hall effect arises from a reactive counterpart of the dissipative spin response that is responsible for the ordinary spin Hall effect. This interpretation is supported by the dependence of spin Hall effect signals on the reversal of magnetic order parameters and can be explained in terms of the symmetries of well-defined linear response functions. This proposal has enabled the generation and manipulation of spin currents electrically. In terms of conversion efficiency, the spin Hall angle is a key parameter used to characterize a material's ability to convert spin currents to charge currents and vice versa. Consequently, there is an ongoing effort to identify mechanisms that can increase the spin Hall angle. In this work, it is proposed a mechanism based on extrinsic surface roughness, which enhances the magnetic spin Hall angle when the ratio of roughness to thickness is high. This mechanism represents an important discovery that will advance the development of charge-to-spin devices. [ABSTRACT FROM AUTHOR] |
