Abstract
We have studied the effect of heterovalent substitution of a Co2+ + Sn4+ combination for Fe3+ on the crystal chemistry and magnetic properties of M-type barium hexaferrite (BHF). The results demonstrate that 2Fe3+ → Co2+ + Sn4+ heterovalent substitution allows one to tune the magnetic properties of M-type BHF (to reduce its coercive force (H c), while maintaining its magnetization (M s) at the level of unsubstituted BHF (x = 0)).Keywords
