Mn–Zn ferrite nanoparticles for application in magnetic hyperthermia
JOURNAL OF RADIOANALYTICAL AND NUCLEAR CHEMISTRY(2021)
摘要
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, Mössbauer spectroscopy, and magnetic hyperthermia system. Among Mn–Zn ferrites, the saturation magnetization of Mn 0.2 Zn 0.8 Fe 2 O 4 reached maximum value (83.2 emu/g). The heating temperature of Mn 0.2 Zn 0.8 Fe 2 O 4 was 118.5 and 48.1 °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.
