Magnetic Rare Earth Compounds

Abstract

Magnetically uniaxial rare earth garnets, such as EuEr2Ga(0.7)Fe(4. 3O12 and Y(1.3)GdYb(0.7)Fe(4.1)Ga(0.9)O12, have been grown by quasi steady-state (isothermal) liquid phase epitaxial techniques. The epitaxial layers have been grown on Syton polished (111) Gd3Ga5O12 substrates by the dipping technique in which the substrates, fastened to a platinum holder, are dipped into the supersaturated growth solution. Both PbO-B2O3 and BaO-B2O3-BaF2 solvents have been employed for the crystal growth, since each has certain distinct advantages and disadvantages for this type of growth situation. The BaO-based solvent has been characterized, and a solubility curve for a typical garnet, EuEr2Ga(0.7) Fe(4.3)O12, has been experimentally determined. The magnetic films have been characterized with respect to solvent content and distribution coefficients of the constituent ions for each of the growth solutions, lattice parameter mismatch between epitaxial layer and substrate, and magnetic properties.
