Abstract

Exchange coupled layers are used with magnetic bubble domain garnet films to suppress "hard" bubbles and to control bubble wall state conversion. Exchange coupled layers of garnet can produce a negative growth induced anisotropy. These garnets are of the type (M R)(3) Fe(5) O(12), where M and R are combinations of La, Y and/or a rare earth.
