dc.description.abstractIn this study, nanocrystalline BaCryFe12?yO19 (0.0???y???1.0) hexaferrite powders were prepared by sol–gel auto combustion method and the effect of Cr3+ ion substitution on morphology, structure, optic and magnetic properties of Barium hexaferrite were investigated. X-ray powder diffraction (XRD) analyses confirmed the purity of all samples. The XRD data shows that the average crystallite size lies between 60.95?nm and 50.10?nm and same was confirmed by Transmission electron microscopy. Transmission electron and scanning electron microscopy analyses presented the hexagonal morphology of all products. The characteristic hysteresis (?-H) curves proved the ferromagnetic feature of as grown nanoparticle samples. Specific saturation magnetization (?s) drops from 46.59 to 34.89?emu/g with increasing Cr content while the coercive field values lie between 770 and 1652?Oe. The large magnitude of the magnetocrystalline (intrinsic) anisotropy field, (Ha) between 11.0 and 12.6?kOe proves that all products are magnetically hard. The energy band gap values decrease from 2.0?eV to 1.84?eV with increasing Cr content. From 57Fe Mössbauer spectroscopy, the variation in line width, isomer shift, quadrupole splitting and hyperfine magnetic field values were determined and discussed.
