Spin dynamics in itinerant antiferromagnet SrCr $_{2}$ As $_{2}$

Zhenhua Ning, Pinaki Das, Y. Lee +6

SrCr $_{2}$ As $_{2}$ is an itinerant antiferromagnet in the same structural family as the SrFe $_{2}$ As $_{2}$ high-temperature superconductors. We report our calculations of exchange-coupling…

Antiferromagnetic domains in a single crystal of the A-type spin-7/2 trigonal topological insulator EuSn $_{2}$ As $_{2}$

Santanu Pakhira, D. C. Johnston

EuSn $_{2}$ As $_{2}$ is a trigonal A-type antiferromagnetic topological insulator with the moments aligned in the $ab$ plane and with a Néel temperature $T_{N} = 23.5$ K. Here we rep…

Coexistence of Ferromagnetism and Antiferromagnetic Dimers in Topological Insulators

Farhan Islam, Deborah Schlagel, Yongbin Lee +6

The addition of magnetic impurities in topological insulators can drive ferromagnetic order that leads to novel quantum anomalous Hall transport well below the Curie temperature. T…
