Magnetic properties and growth conditions of manganese-containing iron garnet films for magnetic bubbles

Abstract
Manganese can be substituted in iron garnet films in order to increase the magnetostriction constants. When these films are grown under compression, magnetic anisotropy is introduced. The influence of manganese on film-growth conditions and magnetic properties has been studied. Phenomenological equations are derived to describe the properties of the manganese-containing garnet films. These equations were successfully applied in a test case of tailoring the properties of garnet films.
