Synthesis and investigation of magnetic properties of Gd-substituted Mn-Zn ferrite nanoparticles as a potential low-TC agent for magnetic fluid hyperthermia

Gd-substituted Mn-Zn ferrite nanoparticles of different compositions were synthesized by chemical co-precipitation method. To study the reduction of the Curie temperature (TC) for different samples, their magnetic properties in dependence from the composition and cationic distribution were investigated. An attempt to lower the TC of superparamagnetic particles to the optimal temperature required in magnetic fluid hyperthermia (44-47 °C) was made.
