STUDY OF THE STRUCTURE AND HEAT GENERATION ABILITY OF Fe2O3 MAGNETIC MATERIALS

Abstract

In recent years, research on the use of magnetic nanomaterials in biomedicine, especially in hyperthermia treatment of tumors, has been developing rapidly. The basic principle of tumor heat therapy is to bring magnetic powder together with other drugs to the site of the tumor and, when exposed to a high-frequency alternating magnetic field, the particles release heat and stop the growth of tumor cells. Magnetic materials with the ability to release heat are powder magnetic materials with ferrimagnetic properties.This article presents the results of a study of the microstructure and heat release ability of iron oxide ferromagnets synthesized by microwaves.
