- Abstract
Ultra-fine nanoparticles of strontium hexaferrite, SrFeO, have been synthesized by low-temperature solid-state reaction method without ball-milling process. The effects of the preparing conditions of samples such as calcination temperature, Fe/Sr and Na/Sr mole ratio on the phase composition, particle size and shape and magnetic properties of the calcined samples have been investigated by differential thermal analysis, X-ray diffraction, field emission scanning electronic microscopy, and vibrating sample magnetometery. The X-ray diffraction patterns showed the formation of SrFeO single phase at temperatures as low as 750° C. Fine particles with particle size around 30-100 nm obtained at 750° C with Fe/Sr mole ratio of 10. The magnetic measurements and structural analysis showed that particles were single domain and exhibited better magnetic properties than those obtained by the ceramic method.
