Mn-Zn ferrite nanoparticles for application in magnetic hyperthermia

Abstract

Mn-Zn ferrite nanoparticles for magnetic hyperthermia applications were synthesized by a high temperature thermal decomposition method. The crystallographic, magnetic, and thermal properties of the prepared Mn-Zn nanoparticles were investigated using a vibrating-sample magnetometer, X-ray photoelectron spectroscopy, Raman, Mossbauer spectroscopy, and magnetic hyperthermia system. Among Mn-Zn ferrites, the saturation magnetization of Mn0.2Zn0.8Fe2O4 reached maximum value (83.2 emu/g). The heating temperature of Mn0.2Zn0.8Fe2O4 was 118.5 and 48.1 degrees C for powder and agar solution at 50 kHz and 250 Oe. These results suggest that the synthesized nanoparticles can be potential candidates for their use in magnetic hyperthermia areas.
