The growth of magnetic garnets by liquid phase epitaxy

Phase relationships in the PbO-B2O3-garnet systems and their relationship to high quality - low defect epitaxial films are discussed. The effects of growth temperature, lattice mismatch and growth rate on the magnetic properties of multiple-doped rare earth iron garnets are shown. Properties of iron garnets containing rare earths, such as Yb, Eu, Er, Y and Gd will be discussed along with magnetic data to indicate the effects of ionic size and stress on magnetic uniaxial anisotropy. Liquid phase epitaxy utilizing super-cooled melts will be discussed in terms of two unique properties of garnets: their tendency to grow free of dislocations and their resistance to spontaneous nucleation from supercooled flux solutions.
