Liquid phase epitaxial growth kinetics of magnetic garnet films grown by isothermal dipping with axial rotation

Abstract

Epitaxial magnetic films of Eu1.1Yb1.9Fe5O12 have been grown under controlled isothermal conditions on (111) Gd3Ga5O12 substrates with and without rotation. The growth kinetics are adequately described by an analytical model involving diffusion (D≅3·10-5 cm2/sec) through a stagnant boundary layer (δ ≅ 100 μm) and subsequent integration into the film according to a first order reaction (k ≅ 3·10-3 cm/sec). These magnetic films support bubbles with a sub-micron diameter under proper bias field conditions. © 1973.
