Recently, giant planar Hall effect originating from chiral anomaly has been predicted in nonmagnetic Dirac/Weyl semimetals. ZrTe5 is considered to be an intriguing Dirac semimetal at the boundary of weak topological insulators and strong insulators, though this claim still remains controversial. Here, we report observation resistivity that shows two different magnetic-field dependences as by theory a maximum Lifshitz transition temperature. We found fades out with decreasing thickness...
