“…Other M-type hexaferrites, strontium and lead hexaferrites (SrM and PbM), have been studied as films [26,27]. Scandium-doped BaM films were deposited to control the magnetic anisotropy, [28] whereas cobalt and titanium co-doped BaM and aluminum-doped SrM films were deposited for the optimization of the magneto-optical properties [29,30].…”
