Magnetic, Mössbauer and hyperthermia properties of Co1−xMnxFe2O4 nanoparticles

Hyperthermia is used to combat and reduce the effects of tumors. This study relates to Co1−xMnxFe2O4 magnetic nanoparticles and their potential in hyperthermia treatment applications. Co1−xMnxFe2O4 nanoparticles were prepared using the high-temperature thermal decomposition method, and the cubic spinel structure with the Fd-3m space group was confirmed through X-ray diffraction analysis. The self-heating temperature was measured using a magneTherm device, and the Mossbauer spectrum covers six lines of sites A and B. Consequently, the composition, particle size, and frequency conditions of magnetic nanoparticles capable of generating self-heating temperatures near the cancer cell death temperature of 42–43 °C were established.
