Injection of Uncompensated Spins by Current in Metallic Magnetic Nanojunctions
摘要
Abstract
The development of spin imbalance during current flow through a magnetic junction with unidirectional magnetization vectors is examined using a spin-injection terahertz emitter (with an array of layered nanowires) as an example. The influence of the magnetic parameters of the layers on the change in the physical state of the magnetic junction is demonstrated. In a general case, the formation of the electrical parameters of the emitter structure that determine the flow of electrons with uncompensated spins is considered. The dependence of the magnetic parameters of the junction on the applied voltage is theoretically estimated and experimentally confirmed.
