Spin–orbit torque (SOT)-induced magnetization switching in ferromagnet/heavy metal bilayers can be realized in three modes, Type-x, Type-y, and Type-z, categorized by the relative orientation between polarization of spin current (σ) and easy axis (EA) of ferromagnet1. Here, σ is generated...
Spin–orbit torque (SOT), which is induced by an in-plane electric current via large spin-orbit coupling, enables an innovative method of manipulating the magnetization of ferromagnets by means of current injection. In conventional SOT bilayer systems, the magnetization switching efficiency strongly de...
Spin–orbit torque switching in a T-type magnetic configuration with current orthogonal to easy axesDifferent symmetry breaking ways determine various magnetization switching modes driven by spin鈥搊rbit torques (SOT). For instance, an applied or effective field parallel to applied current is ...

对于铁磁,利用spin-transfer-torque(SFT)或者spin-orbit-torque(SOT)可以调控磁化方向(从而实现0和1的写入读出)。(注:SFT和SOT差别主要在于定义,其实可以不必纠结。一般前者主要描述直接的自旋流注入,比如spin pumping出的自旋极化的电流(或者是电流通过fixed layer后被polarized)通过spacer后直接流入到下一层铁磁层(...
Spin–orbit torque, a torque brought about by in-plane current via the spin–orbit interactions in heavy-metal/ferromagnet nanostructures, provides a new pathway to switch the magnetization direction. Although there are many recent studies, they all build on one of two structures that have the ea...
In this work, by studying the spin–orbit torque induced switching in the Heusler alloy Mn2Ru1? x Ga, it is found that efficient current‐induced magnetic switching can be realized in a nearly compensated sample with strong perpendicular anisotropy and large film thickness. This work demonstrates...
Spin-orbit torque-induced switching of an elliptical nanomagnet with an in-plane easy axis allows sub-ns and field-free operation. Since its properties crucially depend on the design of the nanomagnet such as the easy-axis direction, it is of high importance to systematically elucidate the depe...
Alternatively, spin–orbit torque can be employed, and switching with current pulses down to ~200 ps has been demonstrated. However, the upper limit to magnetization switching speed remains unestablished. Here, we show that photoconductive switches can be used to apply 6-ps-wide electrical ...
