摘要：
Sr1−xLaxFe12O19 (x = 0, 0.15, 0.25, 0.5) hexaferrites were prepared by microwave-assisted sol-gel method. The thermal decomposition process, structural, and magnetic properties of the products were studied by thermal differential scanning calorimeter (DSC), thermogravimetry (TG), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM). The phase of α-Fe2O3 appeared at x = 0.25 and x = 0.5. The coercivity of La3+-substituted strontium hexaferrites is improved to 5960.2 Oe at x = 0.25.
