摘要: Abstract Strontium M-type hexagonal ferrites were synthesized at different calcination temperatures (800 °C, 1000 °C and 1100 °C) using sol-gel autocombustion method. Thermogravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), Mossbauer spectroscopy (MS) superconducting quantum interference device magnetometer (SQUID) techniques used to characterize crystal structure, phase composition, morphology magnetic properties. TGA gives T = 800 °C as beginning of suitable calcination. Hexaferrite structure single is obtained according XRD results for all samples with crystallite size between 28 nm 35 nm. SEM images show the growth grain increasing annealing temperature. (BH) max calculated based on SQUID shows an enhancement 25%. The properties observed low temperature are explained confirmed by ab-initio calculations.
