Abstract

Using a facile method, Fe/Mo anti-site defect (ASD) concentration in double perovskite Sr₂FeMoO₆ is quantitatively controlled within a wide range of 2%–21%. Our systematic investigation demonstrates the significant effects of ASD on the physical properties, such as magnetization, magnetoresistance and the Curie temperature.
