Turn-on of Current-Induced Spin Torque upon Noncollinear Antiferromagnetic Ordering in Delafossite PdCrO2
Xiaoxi Huang, Qi Song, Gautam Gurung +10
We report measurements of the current-induced spin torque produced by the delafossite antiferromagnet PdCrO2 and acting on an adjacent ferromagnetic permalloy layer. The spin torqu…

Colour symmetry and altermagnetic-like spin textures in noncollinear antiferromagnets
Paolo G. Radaelli, Gautam Gurung
We present a formalism based on colour symmetry to analyse the momentum-space spin textures of non-collinear antiferromagnets. We show that, out of the spin textures allowed by the…
