摘要：

The bulk Ca2CrO4 samples were synthesized under high pressure and high temperature conditions using CaO and CrO2 as starting materials. The structure of the prepared Ca2CrO4 solid is characterized by X-ray diffraction with Rietveld refinement as tetragonal structure with the space group I4(1)/acd. The CrO6 octahedrons elongate along c axis and rotate in ab plane. DC and AC magnetic susceptibility measurement results indicate spin glass behavior at low temperature. Temperature dependence of resistivity measurement results show Ca2CrO4 is an insulator at both ambient condition and high pressure. (C) 2016 Author(s).
