Abstract:

We use resonant elastic x-ray scattering to determine the evolution of magnetic order in EuCd 2 As 2 below T N = 9.5 K, as a function of temperature and applied magnetic field. We find an A-type antiferromagnetic structure with in-plane magnetic moments, and observe dramatic magnetoresistive effects associated with field-induced changes in the magnetic structure and domain populations. Our ab initio electronic structure calculations indicate that the Dirac dispersion found in the nonmagnetic Dirac semimetal Cd 3 As 2 is also present in EuCd 2 As 2 , but is gapped for T < T N due to the breaking of C 3 symmetry by the magnetic structure.
