Madrid) are acknowledged.The phase diagram of the double perovskites of the type Sr_(2-x)La_(x)FeMoO_(6) is analyzed, with and without disorder due to antisites. In addition to an homogeneous half metallic ferrimagnetic phase in the absence of doping and disorder, we find antiferromagnetic phases at large dopings, and other ferrimagnetic phases with lower saturation magnetization, in the presence of disorder.engjournal articlehttp://doi.org/10.1103/PhysRevB.67.214423http://journals.aps.org/open access5351-73Low-field magnetoresistanceSite disorderSr2FeMoO6MagnetizationOxide.Física (Física)Física-Modelos matemáticos22 Física
