Two more experimental papers on the orbital torque
WebHere, we demonstrate a marked enhancement of the spin-orbit torque induced by a fine-tuning of oxygen-induced modification of orbital hybridization. This is evidenced by a concomitant enhancement of the interface spin-orbit torque, interface spin loss, and interface perpendicular magnetic anisotropy within a narrow range of the oxidation level ... WebOct 22, 2024 · We apply our formalism to two different magnetic bilayers, Fe/W(110) and Ni/W(110), which are chosen such that the orbital and spin Hall effects in W have opposite sign and the resulting spin- and orbital-mediated torques can compete with each other. ... (110) is the orbital torque originating in the orbital Hall effect of the nonmagnetic ... butterick 5339
Orbital torque in magnetic bilayers. - Abstract - Europe PMC
WebApr 30, 2013 · 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... WebSo far, the quantitative determination of charge current-induced spin current and spin–orbit torques (SOTs) on the magnetic layer adjacent to two-dimensional materials is still lacking. WebWith this motivation, we examine the current-induced spin-orbit torques in various ferromagnet/heavy metal bilayers by theory and experiment.
