TEXTURED PLANAR M-TYPE HEXAGONAL FERRITES AND METHODS OF USE THEREOF

摘要

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.
