Competing Antiferromagnetic Phases in Multiferroic Wurtzite Transition-Metal Chalcogenides
Himanshu Mavani, Mohamed Elekhtiar, Kai Huang +2
Antiferromagnetic (AFM) spintronics offers a pathway toward electrically controllable spin-based devices beyond ferromagnets. Here, we identify wurtzite MnX (X = S, Se, Te) as a fa…
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…
Longitudinal transport spin polarization of spin degenerate antiferromagnets
Meng Zhu, Jianting Dong, Xinlu Li +4
A vital goal in spintronics is the efficient electrical generation of spin currents, a pursuit that has recently focused on using antiferromagnets (AFMs) as spin current sources. I…
Octupole-driven spin-transfer torque switching of all-antiferromagnetic tunnel junctions
Jaimin Kang, Mohammad Hamdi, Shun Kong Cheung +23
Magnetic tunnel junctions (MTJs) based on ferromagnets are canonical devices in spintronics, with wide-ranging applications in data storage, computing, and sensing. They simultaneo…
Antiferroelectric Hafnia Down to the 2D Limit
Xin Li, Guodong Ren, Haidong Lu +16
Antiferroelectricity is a material property characterized by alternating electric dipoles spontaneously ordered in antiparallel directions. Antiferroelectrics are promising for ene…
