Phase diagram and influence of defects in the double perovskites
arXiv:cond-mat/0210303 · doi:10.1103/PhysRevB.67.214423
Abstract
The phase diagram of the double perovskites of the type Sr_{2-x} La_x Fe Mo O_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.
