Abstract

We report self-controlled heating temperature rising characteristics of gadolinium-substituted zinc iron ferrite magnetic nanoparticles. ZnGdFe ₂O ₃ nanoparticles were synthesized chemically by a co-precipitation process for application as hyperthermia inducing agents. The structure, morphology and magnetic properties of the nanoparticles were characterized using scanning electron microscope, X-ray diffractometer, and superconducting quantum interference device. The magnetic properties investigated included Curie temperature T _c, saturation magnetization M _s, remanent magnetization M _r, coercive field H _c, and hysteresis. It was observed from the study of the synthesized ZnGd ferrite nanoparticles that addition of Gd resulted in an increase in nanoparticles system's overall Curie temperature as well as its pyromagnetic coefficient.
