  • Abstract
    Magnetic properties of amorphous Fe3O4-CaO-SiO2 are described in terms of the microscopic structure. The amorphous region and magnetization strengths for the system were determined, while measurements of the temperature dependence of magnetization revealed no clear Curie temperature; this was attributed to thermal decomposition of the ferrimagnetic crystalline phase. Mossbauer spectra indicated that the material was paramagnetic at room temperature and ferrimagnetic at 4.2 K. It was concluded that Fe3+ in octahedral sites, Fe3+ in tetrahedral sites and Fe2+ interact paramagnetically.
