We examine the effect that a spatially nonuniform spin current with a component polarized partially out of the plane has on a low saturation magnetization nanomagnet free layer. Micromagnetic simulations indicate that the spin-torque efficiency acting upon the reversing nanomagnet can be enhanced through this process, resulting in faster switching with smaller currents. In doing so, we determin...

Weyl semimetals are playing a major role in condensed matter physics due to exotic topological properties, and their coexistence with ferromagnetism may lead enhanced spin-related phenomena. Here, the inverse spin Hall effect (ISHE) ferromagnetic Weyl-semimetal Heusler alloy Co$_2$MnGa was investigated at room temperature by means of electrical injection lateral valve structures. Spin transport...

The giant magnetoresistance (GMR) of ferromagnetic bilayers with a superconducting contact (F1/F2/S) is calculated in ballistic and diffusive regimes. As in spin-valve, it is assumed that the magnetization in the two ferromagnetic layers F1 and F2 can be changed from parallel to antiparallel. It is shown that the GMR defined as the change of conductance between the two magnetic configurations i...

We report a strain effect on spin transport in semiconductors that exhibit $\mathrm{Ge}$-like conduction bands at room temperature. Using four-terminal nonlocal spin-transport measurements lateral spin-valve devices, we experimentally estimate the diffusion length ($\ensuremath{\lambda}$) of $\mathrm{Ge}$ and strained ${\mathrm{Si}}_{0.1}{\mathrm{Ge}}_{0.9}$ with two different carrier concentra...
