Growth and Characterization of Liquid Phase Epitaxially Grown Spinel Ferrite Films

摘要

The characteristics of ferrimagnetic and ferromagnetic materials are reviewed with particular emphasis on the uniaxial magnetic anisotropy which may be presented in liquid phase epitaxy (LPE) grown in spinel ferrite films. The properties of spinel ferrites are explored and the preparation of substrates for the growth of ferrite films are considered. The LPE growth procedure as well as methods for characterizing film thickness and film lattice parameters, composition, and saturation magnetization are described as well as magnetic anisotropies, the magnetic domain configuration and uniaxial anisotropy. The growth of indium substituted magnesium ferrite films, LPE growth of lithium-ferrite-alluminate films, LPE growth of copper ferrite films, stress induced anisotropy in LPE grown Ni(Fe, Al)2O4 films, and the LPE growth of Mn, Ni, and Al-substituted copper ferrite films are discussed.
