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…
