Effect of Heat Treatment Conditions on the Properties of FePt Nanoparticles Produced by Sonochemistry
Main Article Content
Abstract
Magnetic properties of magnetic nanoparticles FePt prepared by sonochemistry were investigated. Upon annealing at temperature from 450ºC to 650ºC samples have ordered L10 structure and show hard magnetic properties. Influence of heat treatment conditions (annealing temperature, cooling rate) on the magnetic properties of the annealed samples has been studied.
Keywords: FePt, nanoparticle, sonochemistry, magnetic properties.
