Multicomponent magnetic particles with controllable electromagnetic properties

Abstract

In this paper, we focus on preparation and investigation of magnetic and dielectric properties of multicomponent particles with core-shell structure comprising of low-anisotropy MnZn ferrite (core) and polyaniline containing nanoparticles of noble metals (shell). The main advantage of such hybrid magnetic materials is that their electromagnetic properties can be effectively controlled by synthesis conditions. Developed materials can find their potential application as magnetic fillers in the preparation of electromagnetic wave absorbers, where high permeability, high magnetic loss, and optimum ratio between the permeability and permittivity are of high importance.
