WebApr 12, 2024 · It has been extensively described that in a spintronic terahertz emitter a femtosecond laser pulse can induce a perpendicular spin current that is then converted by the inverse spin Hall effect into an ultrafast lateral charge-current pulse, and the underlying physics have been thoroughly analyzed. WebSep 26, 2024 · Each interface generates spin currents with polarization along ^z×E, where ^z is the interface normal and E denotes the electric field. The Co/Cu and Co/Pt interfaces additionally generate spin currents with polarization along ^m×(^z×E), where ^m gives the magnetization direction of Co.

Terahertz spin ratchet effect in magnetic metamaterials
WebAug 26, 2024 · Spin current historically referred to the flow of electrons carrying spin information, in particular since the discovery of giant magnetoresistance in the 1980s. Recently, it has been found... Webv. t. e. In quantum mechanics, the probability current (sometimes called probability flux) is a mathematical quantity describing the flow of probability. Specifically, if one thinks of probability as a heterogeneous fluid, then the probability current is the rate of flow of this fluid. It is a real vector that changes with space and time. WebMeanwhile, long spin diffusion lengths and predicted superfluid transport of spin currents in antiferromagnetic insulating oxides in particular are attractive for low-power device operation. Recently, there have been significant research efforts into the control and manipulation of spin-transport in antiferromagnetic heterostructures with both ... stillwater national bank cd rates
