摘要：

We prepared Pb(2)CrMoOG under high pressure and high temperature. The sample has a heavily or fully disordered double perovskite structure (Pm-3m, a=3.9472 angstrom). It shows a weak ferromagnetic behavior (T-c similar to 33 K) and a significant low magnetization (similar to 0.095 mu(B)/f.u. at 7 T and 5 K), which is discussed based on the cation disorder. The temperature dependence of the electrical resistivity of Pb2CrMoO6 exhibits a semiconducting behavior, which could be well understood by the 3D variable range hopping model. No significant magnetoresistance was observed in this sample. 2014 Elsevier Ltd. All rights reserved.
