Spin-Orbit Coupling effects in Antiferromagnets: From the spin Hall effect to electrical and optical writing and reading of reversed Néel vector states in a collinear antiferromagnet

Modern magnetic storage technologies are based on classical spin-transfer magneto resistance and spin transfer torque (STT) effects enabling the detection and manipulation of magnetisation in ferromagnets [1]. A promising new development in spintronics considers antiferromagnets (AFs) as active elements for robust magnetic storage and ultrafast information processing. AFs possess a microscopic staggered magnetic order with no net-magnetization, resulting in much faster dynamics (~THz) than the one of ferromagnets (~GHz) [2,3]. [read more]
