The phase diagrams of double perovskites of the type, Sr2–xLaxFeMoO6, were analyzed, with and without disorder due to antisites. In addition to an homogeneous half metallic ferrimagnetic phase in the absence of doping and disorder, antiferromagnetic phases were found at large doping levels, and other ferrimagnetic phases with lower saturation magnetization, in the presence of disorder.
