Growth and magnetic properties of prism like triangular Fe3O4 nanoparticles

Prisms like triangular Fe3O4 nanoparticles have been synthesized by a hydrothermal method using n-octylamine as the capping agent to control the particle growth of Fe3O4. The crystal structure, particle shape and magnetic properties have been investigated by X-ray diffraction (XRD), atomic force microscopy (AFM) and vibrating sample magnetometer (VSM) studies respectively. The results show that the Fe3O4 nanoparticles exhibit simple cubic inverse spinel structure with Prisms like triangular shape. The edge length of the prism like triangular nanoparticles is about 150 nm. The room temperature ferromagnetic property was obtained.
