Planar Hall effect in Cu intercalated PdTe${}_2$

Abstract

We present the Planar Hall effect studies on the Cu intercalated type-II Dirac semimetal PdTe${}_2$. The electrical resistivity exhibits a positive field dependence both in perpendicular and parallel field directions, causing non-zero anisotropy. The longitudinal magnetoresistance shows almost linear field dependence at low temperatures. A tilted prolate spheroid shaped orbits are observed in parametric plot between transverse and longitudinal resistivities. Our study suggest that for the type-II Dirac semimetal materials with positive longitudinal magnetoresistance, the origin of Planar Hall effect cannot be asserted with certainty to the topological or non-topological without taking into account the anisotropy of Fermi surface.
