Magneto-optical Kerr effect in an A-type antiferromagnet
V. Sunko, S. Ahsanullah, V. Jain +5
Magneto-optic Kerr effect (MOKE) is a powerful probe of broken time-reversal symmetry (), typically used to study ferromagnets. While MOKE has been observed in some an…
MnRhBi3: A Cleavable Antiferromagnetic Metal
Eleanor M. Clements, Dmitry Ovchinnikov, Parul R. Raghuvanshi +10
Cleavable metallic antiferromagnets may be of use for low-dissipation spintronic devices; however, few are currently known. Here we present orthorhombic MnRhBi3 as one such compoun…
Plasmonic polarization sensing of electrostatic superlattice potentials
