Preparation and Magnetic Properties of Parallelepiped -Fe2O3 Nanoparticles

Abstract

Parallelepiped -Fe2O3 nanoparticles with a narrow size distribution were was successfully synthesized by hydrothermal method. The structural and morphological properties of -Fe2O3 nanoparticles were characterized by X-ray diffract meter (XRD), Scanning electron microscope (SEM), and transmission electron micrograph (TEM). The magnetic behavior of the Parallelepiped -Fe2O3 nanoparticles was investigated, the results showed that The parallelepiped nanoparticles possessed the lower remanent magnetization and coercivity than other -Fe2O3 particles with similar size, indicating its potential application in superparamagnetic materials.
