Crystallization of nano-sized barium ferrite.

摘要

he predominant problems in the development of barium ferrite-based magnetic recording media are unacceptably large particle size, wide size distribution, and unacceptably high magnetic coercivity. The latter can be modified by partial substitution of cations. The control of particle size and size distribution, however, remains an issue. To this end, the focus of this research was to investigate the microstructural development of barium ferrite. The research can be broken into three major thrust areas: (1) Effect of
