Spin-Orbit Torque (SOT) Magnetic Random-Access Memory (MRAM) devices offer improved power efficiency, nonvolatility, and performance compared to static RAM, making them ideal, for instance, for cache memory applications. Efficient magnetization switching, long data retention, and high-density ...
Spin-orbit torque switching without external field with a ferromagnetic exchange-biased coupling layer Magnetization reversal of a perpendicular ferromagnetic free layer by spin-orbit torque (SOT) is an attractive alternative to spin-transfer torque (STT) sw... YC Lau,D Betto,K Rode,... - 《Ph...
where the magnetization direction is controlled by passing an electric current. It is found that the spin-orbital interaction induces both an effective field and torque on the magnetization, which have been attributed to two different origins: the Rashba effect and the spin Hall effect. It requires...
The interplay between spin, charge, and orbital degrees of freedom has led to\nthe development of spintronic devices like spin-torque oscillators, spin-log... C Ciccarelli,KMD Hals,A Irvine,... 被引量: 0发表: 2014年 Comment on 'Bose-Einstein Condensation of Magnons in Cs_2CuCl_4' In ...
In order to relate the change in S with time to the Faraday rotation, therefore, we derived an exact torque equation for S. As a result, a magnetic helicity term appeared in a new torque equation for S, so that one-half of the phase shift derived from the helicity term was equivalent...
between applied torque t and limiting angular velocity v lim of a sphere of radius r in a viscous medium of viscosity h is 17 v lim t 8phr 3 . (3) This implies that the absorption of the Tef lon particle is of the order of 2%. The principal motivation of this study was to demon...
