Abstract:
Single phase nano-crystalline particles of strontium hexaferrite have been pleasingly synthesized in one step via a microwave-assisted sol–gel auto-combustion route. The characterization consequences of the research module reveal that synthesized product may have potential applications in the area of magnetic data storage and high-frequency devices. The crystal structure remains unaltered by the Al+3 substitutions. The crystallite size in the range of 14-42 nm is determined from the X-ray diffraction. Scanning electron micrographs of the samples showed homogenous microstructures. The magnetic properties such as saturation magnetization, remanence and coercivity are calculated from the hysteresis loops. The values of saturation magnetization are found to be increase while that of remanence and coercivity showing decreasing trend.
Keywords: nano-crystalline, XRD, saturation magnetization, remanence, coercivity etc.
