Multilayer Epitaxial Garnet Films for Magnetic Bubble Devices-Hard Bubble Suppression

Abstract

A conventional magnetic bubble material consists of a magnetic garnet film deposited on a nonmagnetic substrate. Garnet films with stress- and/or growth-induced uniaxial anisotropy are deposited by chemical vapor deposition (CVD) or liquid phase epitaxy (LPE) usually on Gd <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> Ga <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5</inf> O <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">12</inf> substrates.
