Title: Manipulating magnetism in the topological semimetal EuCd 2 As 2

Abstract

EuCd 2 As 2 is a magnetic semimetal that has the potential of manifesting nontrivial electronic states, depending on its low temperature magnetic ordering. Here, we report the successful synthesis of single crystals of EuCd 2 As 2 that order ferromagnetically or antiferromagnetically depending on the level of band filling, thus allowing for the use of magnetism to tune the topological properties within the same host. We explored their physical properties via magnetization, electrical transport, heat capacity, and angle-resolved photoemission spectroscopy measurements and conclude that EuCd 2 As 2 is an excellent, tunable system for exploring the interplay of magnetic ordering and topology.
