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…

Emergence of Ferromagnetism from Planar Defects in EuSn2As2 Antiferromagnet
A. Yu. Levakhova, A. L. Vasiliev, N. S. Pavlov +6
We report a study of nano-scale structural peculiarities of the antiferromagnetic layered semimetal EuSn2As2, and show that they are responsible for its puzzling magnetic propertie…

Intrinsic Negative Magnetoresistance in Layered AFM Semimetals: the Case of EuSnAs
K. S. Pervakov, A. V. Sadakov, O. A. Sobolevskiy +12
Here, by applying a comprehensive approach including magnetic, transport measurements, ARPES band structure measurements, DFT calculations, and analytical theory consideration, we…
