Structure, magnetic and electrical properties of disordered double perovskite Pb2CrMoO6

• A new double perovskite Pb2CrMoO6 was prepared under high pressure and high temperature conditions.
• Structure, magnetic and electrical properties of synthesized Pb2CrMoO6 were investigated..
• The measured properties of Pb2CrMoO6 are discussed based on cation disorder.

We prepared Pb2CrMoO6 under high pressure and high temperature. The sample has a heavily or fully disordered double perovskite structure (Pm-3m, a=3.9472 Å). It shows a weak ferromagnetic behavior (TC~33 K) and a significant low magnetization (~0.095 μB/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.
