چکیده انگلیسی
Monodisperse SrFe12O19 (SrM) nanoflakes were successfully fabricated via a modified hydrothermal method. The effects of Fe3+/Sr2+ (RF/S) and OHâ/NO3â (RO/N) molar ratio on phase, structure and morphology of the products were investigated by XRD, FT-IR, FESEM, and TEM. Meanwhile, the magnetic properties of the product were investigated via vibrating sample magnetisem (VSM). Results demonstrated that when the RF/S=5 and RO/N=2, the single phase SrFe12O19 particles were obtained. The as-obtained SrFe12O19 particles had monodisperse nanoflake structure and nano-micro scale in vertical and horizontal direction of SrM ferrite particle. The magnetic property results showed that such structure SrM ferrite particle had prospective saturation magnetization and coercivity, the largest values of Ms and Hc were 62.96Â emu/g and 94.83Â kA/m, respectively, which make it have a potential application as magnetic recording media and magneto-optical devices material.
