A Study of magnetic efficiency from composite materials for industrial use

Abstract

The magnetic properties of Ba2FeMoO6 (BFMO) BaCO3 (Barium carbonate, 99.9%), Fe(NO3)3.9H2O (Iron(II) nitrate, 99.0%) and Mo03 (Molybdenum trioxide, 99.0%) have been characterized. A slurry was prepared by mixing the powders with deionized (DI) water at a ratio of 1:7.5: by solid state reaction method through compression. In the case of BFMO, sintering at 800 °C for a 4, 6 and 10 hours. exhibited the largest hysteresis loop at 50 K. In addition, the values of Ms and Mr indicate ferromagnetic behaviour in BFMO ceramics sintered from 600 °C to 800 °C. Finally, the value of magnetization was reduced by using a lower sintering temperature, SEM analysis revealed the physical appearance of sintered BFMO ceramic, and showed the morphology of the BFMO powder was. coarse with an average diameter of 2 microns
