Abstract :
The temperature dependence of coercivity for (Ti,Co)-substituted barium ferrites between 77 and 500 K is found to be substantially different from that of nonsubstituted material. This difference can be accounted for by a much steeper decrease of the magnetocrystalline anisotropy field component and by the possibility that the magnetization reversal mechanism varies from coherent to incoherent as the temperature is varied
