In this work, the Sr_1-xCa_xFe_12-yZn_yO₁₉ (x = 0, 0.05, 0.1, 0.15; y = 0, 0.25, 0.5, 0.75) hexaferrite were prepared employing the sol-gel combustion method and their structural, magnetic and optical properties were investigated. The formation of the hexaferrite phase was confirmed in all the samples using the X-ray diffraction and Fourier transform-infrared spectroscopy measurements. The field emission scanning electron microscopy images revealed agglomerated particles with rod-like shapes. A vibrating sample magnetometer was used to record the hysteresis loop at room temperature. The results obtained showed a drop in the saturation magnetization from 47.14 to 21.02 emu/g upon an increase in the substitution concentration and an increase in the coercivity from 5520 Oe to 5645 Oe. The bandgap energy values were obtained using the reflectance spectra; they increased from 1.59 eV to 1.72 eV with an increase in the substitution contents.

在这项工作中，Sr _1-x Ca _x Fe _12-y Zn _y O ₁₉（x = 0，0.05，0.1，0.15; y = 0，0.25，0.5，0.75）采用溶胶-凝胶燃烧法制备了六铁氧体，并对其结构，磁性和光学性质进行了研究。使用X射线衍射和傅里叶变换红外光谱法测量，在所有样品中均确认了六价铁氧体相的形成。场发射扫描电子显微镜图像显示具有杆状形状的附聚颗粒。使用振动样品磁力计记录室温下的磁滞回线。获得的结果显示，随着取代浓度的增加，饱和磁化强度从47.14 emu / g降低至21.02 emu / g，矫顽力从5520 Oe升高至5645 Oe。使用反射光谱获得带隙能量值。它们从1.59 eV增加到1。
