Anomalous and Topological Hall Effects in Antiferromagnetic EuSn2As2 Nanostructures
Evgeny I. Maltsev, Nicolas Pérez, Romain Giraud +8
We investigate magnetotransport in exfoliated nanostructures of the candidate magnetic 3D topological insulator . Similar to macroscopic single crystals, t…

Universal negative magnetoresistance in antiferromagnetic metals caused by symmetry breaking of electron wave functions
Pavel D. Grigoriev, Nikita S. Pavlov, Igor A. Nekrasov +5
Layered van der Waals crystals of topologically non-trivial and trivial semimetals with antiferromagnetic (AFM) ordering of magnetic sublattice are known to exhibit a negative magn…
