Structure and Magnetic Properties of SrFe_12-xIn_xO₁₉ Compounds for Magnetic Hyperthermia Applications.

ABSTRACT: In this work, complex studies of the structure and magnetic properties of SrFe_12-xIn_xO₁₉ powders obtained by the mechanochemical and citrate methods were carried out. The solubility of In in strontium hexaferrite SrFe₁₂O₁₉ at 1200 °C was determined. The structure and properties of the powders were studied using X-ray diffraction analysis, Mössbauer spectroscopy and scanning electron microscopy. Measurements of magnetic properties in magnetic fields up to 1600 kA/m were also performed. Additionally, the hyperthermia effect was investigated. The possibility of controlling the coercivity of the samples in the range from 188.9 kA/m to 22.3 kA/m and saturation magnetization from 63.5 A·m²/kg to 44.2 A·m²/kg with an increase in the degree of
