Abstract

We measured the magnetoresistvity (MR) properties of the 1T`-MoTe2 single crystal under the magnetic field up to 33 T.By analyzing the Shubnikov de Haas oscillations of MR at the low temperature, single Fermi surface is revealed.From the strong oscillatory component of the longitudinal resistance {\Delta}Rxx,a linear dependence of the Landau index n on 1/B is obtained.The intercept of the Landau index plot is between 3/8 and 1/2.This clearly reveals a nontrivial {\pi} Berry`s phase, which is a distinguished feature of Dirac fermions. Accompanied by the superconductivity observed at TC=0.1 K, 1T`-MoTe2 may be a promising candidate of the topological superconductor.
