Direct imaging and control of Berry curvature in noncollinear antiferromagnetic single-crystal thin films
Yuchuan Yao, Pratap Pal, Camron Farhang +11
The discovery of the intrinsic anomalous Hall effect (AHE) in noncollinear antiferromagnets where transverse Hall voltage emerges without magnetic field, has opened a plethora of p…
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…
Nearly perfect spin polarization of noncollinear antiferromagnets
Gautam Gurung, Mohamed Elekhtiar, Qing-Qing Luo Ding-Fu Shao +1
Ferromagnets with high spin polarization are known to be valuable for spintronics--a research field that exploits the spin degree of freedom in information technologies. Recently,…
Symmetry-controlled orbital Hall effect in IrO
Michael Patton, Dongwook Go, Daniel A. Pharis +7
Recent discovery of orbital currents in several material platforms including light element metals has opened new possibilities for exploring novel transport phenomena and applicati…
