Abstract

The temperature dependence of resistance of CrSiTe3 single crystals shows a cusp below the Cure temperature, which may be attributed to the disappearance of electron scattering on magnetic fluctuation. The magneto-conductance of CrSiTe3 was measured at temperatures ranging from 50 K to 30 K over the magnetic field range of 0–5 T. Magneto-transport measurements demonstrate that the low-field negative magneto-conductivity results from the weak anti-localization (WAL). The WAL effect was analyzed based on the Hikami-Larkin-Nagaoka (HLN) two-dimensional (2D) diffusive transport theory and the HLN equation could well fit the magneto-conductivity data.
