Conductivities are key material parameters that govern various types of transport (electronic charge, spin, heat and so on) driven by thermodynamic forces. Magnons, the elementary excitations of the magnetic order, flow under the gradient of a magnon

The spin Hall angle (SHA) represents the efficiency of the conversion between spin current into charge current and vice-versa. In this paper, we report the experimental detection of large enhancement of the effective SHA in heterostructures of yttriu

In recent years several experimental observations and theoretical predictions of unique phenomena involving the interplay between spin currents and the coupled magnetization-elastic dynamics have invigorated the field of spintronics. One important ex

We report the control of the modulation efficiency of the magnon conductivity in yttrium iron garnet (YIG) using magnon spin injection from a ferromagnetic metal permalloy (Py) used as a modulator in a three-terminal magnon transistor geometry. The m

Enhancements in the spin Hall magnetoresistance (SMR) close to one order of magnitude in bilayers of yttrium iron garnet (YIG) and platinum with embedded metallic nanoparticles of Ag and Cu are reported. The enhancement in the electrical detection of

This article shows that the spin-to-charge current conversion in single-layer graphene (SLG) by means of the inverse Rashba-Edelstein effect (IREE) is made possible with the integration of this remarkable 2D-material with the unique ferrimagnetic ins

We report the spin-to-charge current conversion in an intrinsic topological insulator (TI) ${(\mathrm{B}{\mathrm{i}}_{0.22}\mathrm{S}{\mathrm{b}}_{0.78})}_{2}\mathrm{T}{\mathrm{e}}_{3}$ film at room temperature. The spin currents are generated in a t
