Effect of High Magnetic Field on Ferrite Materials Obtained by Calcination of Layered Double Hydroxide

Abstract

In this paper, the effect of high magnetic field on the development of property were investigated by calcination of MgFe-LDH (CO₃) as a precursor of ferrite material under applied field of 10 T. Obtained products were identified by X-ray diffraction analysis (XRD) and their microstructures were observed using scanning electron microscopy (SEM). Furthermore, their magnetic properties were evaluated by a superconducting quantum interference device (SQUID). It was observed that the particle size of mixed oxide prepared by calcination under 10 T was homogeneous and small. Saturation magnetization of mixed oxide synthesized under 10 T was higher than that of zero field. Therefore, it was found that calcination due to imposition of high magnetic field affected phase transition to mixed oxide and provided enhancement of its property.
