Magneto-transport properties of antiferromagnetic Weyl semimetal CuMnSb

POSTER

Abstract

The electrical resistivity and magneto-transport properties of reported magnetic Weyl semimetal CuMnSb is studied. CuMnSb with an antiferromagnetic transition at 60K is synthesized using solid state reaction technique and crystallizes in cubic lattice structure with space group F-43m (216). No abrupt change in resistivity is observed below the transition under the application of 5T field. A highest non-saturating MR of 4% is observed at 5K and 6T. It is analyzed that MR in CuMnSb arises from the contribution of linear field B dependence as well as the parabolic B2 term.
