Sigales, Dominik, electrical spin injection and the separation of charge and spin currents rely either on ferromagnets1,这一行为在两种不同的电偏置几何构型中均被观察到,3,20, Helena, Ismala,15,计算给出的自旋极化率为6.510%, Rial, 研究组证明, 附:英文原文 Title: Time-reversal-symmetry-breaking spin injection from a compensated magnet Author: Mencos,7, we electrically inject spins from Mn5Si3 into a non-magnetic channel and detect their propagation at a spatially separated ferromagnetic electrode. Switching between time-reversed magnetic states of Mn5Si3 reverses the detected spin signal, Gomonay, in which spin polarization originates from a net magnetization,21. The calculations yield spin polarizations of 6.510%,19, whereas the spin-transport modelling of the experiments indicates spin diffusion lengths of 50130nm. Our results provide experimental evidence that a compensated magnet can generate spin currents controlled by its magnetic order and demonstrate that the altermagnetic properties of Mn5Si3 enable spintronic functionality without net magnetization.
