摘要：

The glass crystallization method is shown to be suitable for preparing BaFe12−2x-Cox TixO19 powders with a nearly perfect crystallographic structure and a narrow particle size distribution. The dependences of the specific magnetization, the coercivity, and the particle size distribution on both the annealing temperature and the Co-Ti content correlate in a characteristic way. Furthermore the lattice parameters, the specific surfaces and the thickness of the effective nonmagnetic surface layer were determined. The coercivity of the hexaferrite magnetic tapes is more than 8 × 103 A/m higher than for the the corresponding powders. © 1990 IEEE
