摘要：
We report the magnetism properties on single crystal of Ca2FeMoO6 double perovskite prepared by a floating zone technique. This high quality material has been studied by X-ray powder diffraction (XRD), and magnetic measurements. The field dependence of the magnetization at 5 K, 100 K, and 300 K suggest a ferrimagnetic behavior with a saturation magnetic moment of approximately 2.1 mu(B), 2.0 mu(B), and 1.4 mu(B) per formula unit, respectively. From dc susceptibility, we observed two magnetic transitions at T-C1 = 380 K (paramagnetic-ferrimagnetic) and T-C1 = 336 K (orthorhombic-monoclinic phase).
