Study of Structural Features and Thermal Properties of Barium Hexaferrite Upon Indium Doping / F.G.Agayev, M.N.Mirzayev, [a.o.] // Journal of Thermal Analysis and Calorimetry [Electronic resource]. – 2022. – Vol.147, No.24. – P.14107-14114. – URL: https://doi.org/10.1007/s10973-022-11742-5. – Bibliogr.:73.

The crystal structure, magnetic and thermal properties of M-type BaFe11.9In0.1O19-doped hexaferrite were investigated. It was found that the crystal structure of this solid solution has hexagonal symmetry with P63/mmc space group (No 194) and a = 5.8992(1) Å, c = 23.2275(7) Å unit cell parameters. It was determined that the average grain size is d¯¯¯ = 6 μm. The ferromagnetic-paramagnetic phase transition occurs near TC = 420 °C. It was also established that the water steams that react in active centers are shattered on the surface as a result of the solvothermic reaction being in a weak mutual influence on the temperature interval 30 ≤ T ≤ 317 °C. Thermal transitions repeated as the temperature rises to the highest available values have been established. The oxidation behavior was determined using thermogravimetric spectra in a wide temperature range.
