Novel Electronic Structure Signature across Antiferromagnetic Transition in Rare Earth Monopnictide NdSb

POSTER

Abstract



Rare Earth Monopnictides (REM) are a family of materials that have drawn interest for their possession of topological Dirac behavior and magnetic ordering. Band dispersion and Fermi surface mapping across the paramagnetic to antiferromagnetic phase transition in the REM NdSb was obtained through Angle-Resolved Photoemission Spectroscopy and compared with first-principles density functional theory calculations. Predicted features of the density functional theory calculations are found to be present in the ARPES spectrum, however additional unpredicted signatures in the antiferromagnetic phase were observed as well. These observations append the list of complex many-body effects associated with magnetic ordering.
