M-type hexaferrite having a planar anisotropy
In an aspect, an M-type ferrite comprises an element Me comprising at least one of Ba, Sr, or Pb; an element Me′ comprising at least one of Ti, Zr, Ru, or Ir; and an element Me″ comprising at least one of In or Sc. In another aspect, a method of making the M-type ferrite can comprise milling ferrite precursor compounds comprising oxides of at least Co, Fe, Me, M3′, and Me″ to form an oxide mixture; wherein Me comprises at least one of Ba, Sr, or Pb; Me′ is at least one of Ti, Zr, Ru, or Ir; and Me″ is at least one of In or Sc; and calcining the oxide mixture in an oxygen or air atmosphere to form the ferrite.
