Abstract

The morphology, crystal structure, and thermal and magnetic properties of BaFe11.7In0.3O19 compound have been investigated. As a result of the structure investigations performed by x-ray diffraction method, it was determined that the crystal structure of this compound has hexagonal symmetry with P6(3)mmc space symmetry at normal condition and room temperature. Temperature dependence of specific magnetic moment of BaFe11.9In0.1O19 compound has been established using magnetometry method. It was determined that ferrimagnetic-paramagnetic phase transition occurs at T-C similar to 410 degrees C temperature. Ferrimagnetic-paramagnetic phase transition was studied from DSC spectrum and thermodynamical parameters of phase transition were determined. Thermophysical studies on the BaFe11.9In0.3O19 compound have shown that thermal transitions occur by a complex mechanism. There were decomposition parts determined from the kinetics of DSC spectra: T <= 50 degrees C rapid decomposition, T <= 430 degrees C slow decomposition, and T <= 830 degrees C rapid decomposition parts.
