Abstract

SrFe12O19 magnetic nanoparticles (MNPs) were synthesized by a sol-gel self-propagating method and subsequent heat treatment. The SrFe12O19/NiZnFe2O4 core/shell MNPs were obtained by coating the SrFe12O19 MNPs by glyoxilate precursor method using metallic nitrates and ethylene glycol. The core/shell was characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM) techniques. Comparison of the observations with theoretical criteria indicated that the demagnetization behavior of composite NPs is in exchange spring mode. This phenomenon is attributed to the overcritical size, 46 nm, of the hard phase, which leads to partial exchange coupling between hard- and soft-magnetic phases.
