Abstract
We have investigated temperature-dependent magnetic hysteresis loop behavior of Ba 2- x La x FeMoO 6 with double perovskite structure by means of a vibrating sample magnetometer (VSM). As partial substitution of Ba 2+ by La 3+ is varied from x = 0.1 to 0.3, T C is found to increase from 324 to 345 K. Interestingly, however, hysteresis loop area, remanent magnetization, and coercivity are found to follow a universal behavior with respect to a temperature variation regardless of the Ba 2+ substitution.
