The experimental realization of topological semimetals in the past decade has brought them to the new frontier of condensed matter research. In this paper, we study the angle dependence of the magnetoresistance and planar Hall effect of type-II Dirac semimetal PtTe2 microflakes. The magnetotransport properties of a PtTe2 device are characterized at various temperatures (T = 10–300 K) and different magnetic fields (H = 1–9 T). Remarkable anisotropic magnetoresistance and planar Hall resistance are observed, which can be ascribed to the anisotropic orbital magnetoresistance. Our work provides a comprehensive analysis on the transport properties of PtTe2 and paves the way for its application in the future.
