Optimization of Flux Composition for Thick YIG Layers

Abstract

Thick, nominally pure (only lead substituted) Y 3Fe 5O 12 (YIG) films have been grown on gadolinium gallium garnet (GGG) substrates 2 inches in diameter by isothermal dipping method of liquid phase epitaxy from lead-borate melt. If the liquidus temperature of the melt and the supercooling are varied over in a wide range, 1151-1319 K and 10-48 K, respectively, and one examines the supercoolability of the melt, the lattice parameter, Pb content, FMR linewidth and the surface quality of the prepared layer it can be stated that nominally pure YIG layer on GGG substrate 50 mm in diameter can be grown by only one dipping step up to about 80 μm in thickness without surface defects. © 1987 Akadémiai Kiadó.
