Abstract
In this research, strontium hexa-ferrite nanoparticles (SrFe12O19) were synthesized by sol-gel method. The crystal structure, morphology and magnetic properties of nanoparticles were investigated using X-ray Diffraction (XRD), Scanning Electron Microscope (SEM) and Vibrating Sample Magnetometer (VSM). The XRD patterns confirmed the formation of single phase M-type hexagonal crystal structure for powders which was calcined above 700oC. The product shows the magnetization of 66 emu/g, which is consistent with pure hexa-ferrite obtained by other methods, and the magnetic coercivity of 6,145 kOe higher than expected for this hexa-ferrite. The powder morphology is composed of aggregates of hexagonal particles with an average particles size of above 100nm.
