Abstract
Antiferromagnets are enriching spintronics research by many favorable properties that include insensitivity to magnetic fields, neuromorphic memory characteristics, and ultra-fast spin dynamics. Designing memory devices with electrical writing and reading is one of the central topics of antiferromagnetic spintronics. So far, such a combined functionality has been demonstrated via 90° reorientations of the Néel vector generated by the current-induced spin-orbit torque and sensed by the linear-response anisotropic magnetoresistance. [1, 2] In my presentation I will show electrically control and detection of 180° Néel vector reversals in a collinear antiferromagnet with broken time reversal and spatial inversion symmetries.
