Abstract
The effects of sodium ions added before and after calcination of copre cipitated hexagonal Sr-ferrite are investigated. The values of importa nt performance parameters, namely, energy product (BH)(max), remanence (B-r) and coercivity (H-b(c), H-l(c)) are significantly improved when sodium ions are added after calcination. The better magnetic properti es are assigned to the improved microscopic (structural and chemical) homogeneity and sintered density.
