Magnetism of the double perovskite Sr2FeMoO6

Journal of Magnetism and Magnetic Materials, 2003
Abstract We have completed a systematic study of the magnetization of a single crystal of double perovskite Sr 2 FeMoO 6 over a wide range of temperatures and fields. Near the ordering temperature of 405.0 K, the magnetization is described by critical exponents β =0.50±0.03 and γ =1.20±0.03.
