عنوان	SrFe12O19 ferrites and hard magnetic PVA nanocomposite: investigation of magnetization, coecivity and remanence
نوع پژوهش	مقاله چاپ‌شده
کلیدواژه‌ها	SrFe12O19, hard magnetic, PVA nanocomposite
چکیده	In this work, various morphologies of SrFe12- O19 (SrFe) nanostructures were synthesized via a simple sol–gel method. The effect of concentration, temperature and various surfactants on the morphology and particle size of the magnetic seeds was investigated. The prepared magnetic products were characterized by X-ray diffraction, scanning electron microscopy, and Fourier transform infrared spectroscopy techniques. Alternating gradient force magnetometry reveals that the samples exhibit hard magnetic property with the coercivity up to 5300 Oe. Strontium ferrite was added to poly vinyl alcohol to prepare the magnetic polymeric matrix thin film nanocomposites. The saturation magnetization and coercivity decreased due to agglomeration of magnetic nanoparticles in polymer matrix.
