摘要: In this study, controllable morphology evolution of hexagonal strontium ferrite (SrFe12O19) micro/nano-crystals has been demonstrated. Single phase platelets with were successfully prepared by conventional ceramic process. the crystals, it is revealed that anisotropic growth rate changed, increasing ball milling time, from relatively high along direction (c-axis) to direction, leading evolution. Moreover, optimal saturation magnetization (MS) 69.5 emu/g, which intensely close theoretical value (72 emu/g). This study provides direct evidence enhanced reaction activity induced energy in hexaferrite and obtained SrFe12O19 particles are promising for hard magnet application magnetoelectric electronics.
