The magnetic properties of Ba2FeMoO6 (BFMO) double perovskite are investigated. BFMO samples were prepared by solid state reaction method through compression. Magnetic properties are influenced by electron environments of the Fe3+ and Mo5+ ions within the perovskite structure. BFMO sintered at 800 oC exhibited the largest hysteresis loop at 50 K. In addition, the values of Ms and Mr indicate ferromagnetic behaviour in BFMO ceramics sintered at 800 oC for different times up to 10 hours. Using the Curie-Weiss law fitting to investigate μeff~30μB high spin of Fe and Mo, and negative θ present the antiferromagnetic characteristics of the BFMO sample.

The magnetic properties of BaFeTiO3 (BTFO) perovskite are investigated. BTFO samples were prepared by solid state reaction method through compression. Magnetic properties are influenced by electron environments of the Fe3+ ions within the perovskite structure. Furthermore, the values of Ms and Mr indicate ferromagnetic behaviour in BFMO ceramics sintered at 800 oC for sintering as 800 oC for 6 hours at 1.898 emu/g, which is magnetization strength material more than sintering at 4 hours, 8 hours, 10 hours as 1.794 emu/g, 1.333 emu/g and 1.192 emu/g at measured of low temperature. Using the Curie-Weiss law fitting for investigate μeff~38μB high spin of Fe, negative of θ present to antiferromagnetic characteristics of BTFO sample. Finally, BTFO sintering at the high temperature of 800 oC for 6 hours exhibited the high Ms~1.898 emu/g at 50 K and ~1.216emu/g at room temperature.
