Monte Carlo simulation studies were performed to examine the implications of octahedral cation antisite disorder for magnetization in the double 1:1 perovskites A2+(B1 3+1/2B2 5+1/2) O3: Sr2FeMoO6 (SFMO) and Pb2FeNbO6 (PFN) at finite temperature. The percolation approach was applied at 0 K. We found that about 14.5 % of antisite defects is a critical value for the properties of the 1:1 double perovskites.
