Temperature dependence of magnetic properties of a polymer bonded magnetic material

Abstract

Polymer bonded magnetic materials have recently attracted increasing attention from fundamental research to industrial applications in many electromagnetic devices. It is necessary to investigate the properties of these magnetic materials operated under different environmental conditions. In particular, in this work, we investigated the relationship between the temperature and the magnetic properties of a polymer bonded magnetic material, epoxy (EP) resin bonded Co-Ni magnetic material. Experimental results indicate that the coercivity, the remanence magnetic flux density and the saturation magnetic flux density decrease at the elevated temperature. It is envisioned that the present studies may offer guidance for the applications of the polymer bonded magnetic material.
