  • Textured planar m-type hexagonal ferrites and methods of use thereof
    Patent number: 11508503
    Abstract: A grain-oriented M-type hexagonal ferrite has the formula MeFe12O19, and a dopant effective to provide planar magnetic anisotropy and magnetization in a c-plane, or a cone anisotropy, in the hexagonal crystallographic structure wherein Me is Sr+, Ba2+ or Pb2+, and wherein greater than 30%, preferably greater than 80%, of c-axes of the ferrite grains are aligned perpendicular to the c-plane.
    Type: Grant
