Abstract
Fe-doped SBA-15 magnetic materials was synthesized by pH-adjusting method, and then characterized by X-ray diffraction (XRD) and vibrating sample magnetometer (VSM). All results showed that the samples presented ferromagnetism and the magnetism improved with the Fe content. Saturation magnetization and coercivity of the as-prepared Fe-doped SBA-15 samples increased with the calcined temperature up to 850 °C, followed by decreasing. Furthermore, the magnetic properties at lower temperature (measured at 100 K) of the Fe-doped samples was presented. Finally, the type of the intergranular exchange interaction was conformed by plotting Henkel (δM) formulation.
