Resonant x-ray scattering study of diffuse magnetic scattering from the topological semimetals EuCd2As2 and EuCd2Sb2

Abstract:: We have investigated the magnetic correlations in the candidate Weyl semimetals EuCd2Pn2 (Pn=As, Sb) by resonant elastic x-ray scattering at the Eu2+ M5 edge. The temperature and field dependence of the diffuse scattering of EuCd2As2 provide direct evidence that the Eu moments exhibit slow ferromagnetic (FM) correlations well above the Néel temperature. By contrast, the diffuse scattering in the paramagnetic phase of isostructural EuCd2Sb2 is at least an order of magnitude weaker. The FM correlations present in the paramagnetic phase of EuCd2As2 could create short-lived Weyl nodes.
