MnBi2Te4 has an appealing combination of topological bands and magnetic ordering. While chemical doping with Sb can be used to tune these properties, it typically comes with an increase in defect density. Here, Chen, Wang, Li, Duan, and coauthors demonstrate a defect engineering approach that preserves the topological and magnetic properties of Mn(Bi1-xSbx)2Te4.
