Band structure reconstruction in rare-earth monopnictides in the magnetically ordered state.
ORAL
Abstract
Many members of rare-earth monopnictides exhibit antiferromagnetic transition at low temperatures, with some having more than one magnetically ordered state. Recently, the existence of several types of topologically non-trivial states, including Wely semimetal, were predicted to occur in several of these compounds with signatures of topological states observed in transport measurements and STS measurements. Our ARPES data revealed complex reconstruction of band structure upon development of long range order with some features consistent with presence of topological states.
