Temperature dependence of hard magnetic properties of FePd nanoparticles prepared by sonoelectrochemistry

Abstract

Hard magnetic properties of magnetic nanoparticlesFePd were investigated in dependence of temperature. Magnetic nanoparticles FePd were prepared from palladium acetate and iron acetate by sonoelectrochemistry, an usefultechnique to make metallic nanoparticles using ultrasound. Upon the annealing at 450°C to 650°C samples have ordered L10structure and show hard magnetic properties with high coercivity up to2.1 kOe at room temperature and increases to 2.43 kOe with decreasing temperature down to 2 K
