The spin Hall effect (SHE)1–5 achieves coupling between charge currents and collective spin dynamics in magnetically ordered systems and is a key element of modern spintronics6–9. However, previous research has focused mainly on non-magnetic mate

Oxide interfaces are a source of spin-orbit coupling which can lead to novel spin-to-charge conversion effects. In this Rapid Communication, the contribution of the $\mathrm{B}{\mathrm{i}}_{2}{\mathrm{O}}_{3}$ interface to the anomalous Hall effect (

We study the mechanisms of the spin Hall effect (SHE) and anomalous Hall effect (AHE) in 3$d$ ferromagnetic metals (Fe, Co, permalloy (Ni$_{81}$Fe$_{19}$; Py), and Ni) by varying their resistivities and temperature. At low temperatures where the phon

A kinetic model of oriented nucleation under nonhydrostatic stress: Implications for the preferred orientation of columnar and platy minerals in metamorphic rocks

We propose a kinetic model for the nucleation rate of columnar and platy minerals in nonhydrostatically stressed metamorphic rocks. Nucleation rate I in our model is expressed as I T , σ n = A exp − Δ U ∗ − T Δ S ∗ + σ n Δ V ∗ k B T ,

Detection of the interfacial exchange field at a ferromagnetic insulator-nonmagnetic metal interface with pure spin currents

Publikováno v: Physical Review B. 98

At the interface between a nonmagnetic metal (NM) and a ferromagnetic insulator (FI) spin current can interact with the magnetization, leading to a modulation of the spin current. The interfacial exchange field at these FI-NM interfaces can be probed
