Crossover from Positive to Negative Spin Hall Signal in a Ferromagnetic Metal Induced by the Magnetization Modulated Interface Effect (Adv. Phys. Res. 9/2023)

Spintronics The interplay between charge-to-spin conversion and magnetism is a long-standing unsettled issue in spintronics. In article number 2300017, Zhe Yuan, Jian-Wang Cai, and co-workers expermentally demonstrate, for the first time, that the spin Hall angle of a ferromagnetic metal (Fe) can be gradually reversed by controlling its magnetization. This marks an important advance in ferromagnetic-metal-based spin-orbitronics.
