The Synthesis and Characterization of SmCo Magnetic Nanoparticle by Thermal Decomposition

Abstract

The magnetic nanoparticle of SmCo was synthesized as thermal decomposition of metal salt by using pyrex bottle in the furnace. The magnetic properties of SmConanoparticle were compared according to the ratio of Sm and Co component. The size of nanoparticle was confirmed by transmission electron microscopy (TEM) and scanning electron microscopy images (SEM). The crystal structure of nanoparticle was characterized by X-ray diffraction pattern (XRD). The magnetic properties were characterized with saturation magnetization from hysteresis loop by vibrating sample magnetometer (VSM).
