Phase stability and magnetic properties of SrFe18O27 W‐type hexagonal ferrite

W‐type SrFe22+Fe163+O27 ferrite is a member of the hexagonal ferrite family and a potential permanent magnet material. However, its synthesis conditions are not fully understood yet. Samples were sintered either at 1400°C in air and quenched, or at 1300°C at reduced oxygen partial pressure. The prec...
