摘要

Magnetic nanocrystalline Ni-Zn-Mg-ferrite was synthesized by using the sol–gel method. A cubic spinel-like structure is revealed by XRD and FT-IR investigation of the material. This ferrite’s microstructure was examined using a morphology study. Additionally, the ferrite sample was generated with the correct stoichiometry and no impurities, according to energy-dispersive spectroscopy (EDS) examination. The Ms value was 63.7 emu/g, it was found from magnetic investigations. By providing an alternating magnetic field (varying from 167.13 to 251.32 to 334.27Oe) with a static frequency of 277 kHz, a novel magnetic quaternary metal oxide aids in achieving the target hyperthermia (HT) performance of 42–46 °C in 10 min. Additionally, at an applied field of 334.27Oe at a frequency of 277 kHz, these magnetic ferrites show a specific absorption rate (SAR) of 58.90 W/g at a minimum concentration of 10 mg/ml. The novel magnetically stable Ni0.5Zn0.2Mg0.3Fe₂O₄ nanoparticles were being investigated here for potential use in cancer treatment via magnetic hyperthermia and targeted drug delivery. These materials are a type of ferrospinel with specific magnetic properties that make them highly promising for these biomedical applications.
