英文摘要We have investigated in-plane magnetotransport properties of trigonal layered PtBi2, which was proposed to be a triply degenerate semimetal. A remarkable planar Hall effect was observed in both PtBi(2 )bulk and nanoflake samples. We attribute the planar Hall effect in the bulk sample mainly to a chiral anomaly, manifested by the transport signatures of large negative longitudinal magnetoresistance and the quadratic field dependence of magnetoresistance for the field is parallel to and perpendicular to the current case, respectively. For PtBi(2 )nanoflake, however, further analysis suggests that the in-plane anisotropic orbital resistance rather than the chiral anomaly may play a dominant role on the planar Hall effect. Our results not only give insight into the electronic properties of chiral fermions in triply degenerate semimetal PtBi2, but also provide a promising platform for understanding the mechanism of the planar Hall effect.
