Magnetic property of hierarchical microspheres of Sm2O3 nanoparticles

Sm2O3 microspheres were synthesised by calcination of the corresponding hydrothermally prepared precursors. The structures and morphology were characterized by X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), (field effect) scanning electron microscopy ((FE)SEM) and vibrating sample magnetometer (VSM). Results show that the as-obtained products were assembled by hierarchical microspheres of Sm2O3 nanoparticles and possess an average diameter of about 1.8 µm. These microspheres have superparamagnetic property.
