Abstract
A double perovskite Pb2FeReO6 was prepared at a high pressure (6 GPa) and high temperature (1000°C) condition. The crystal structure determined by the synchrotron X-ray powder diffraction study was centrosymmetric with the space group I4/m despite the presence of Pb2+ ion in the A site. No structural transition to the lower symmetry was observe down to 23 K. This compound exhibited a ferrimagnetic transition at 420 K. The saturation magnetization varied with the degree of Fe3+/Re5+ ordering.
