Abstract

Garnet double-layer structures have been studied with the magnetization axis in-plane in the inner layer and perpendicular in the outer layer, to improve the performance of a parallel high density magnetooptical read head. The system consisting of (GdPrTmBi)₃(FeGa)₅O₁₂ film on (GdCa) ₃(GaMgZr)₅O₁₂ substrate has been improved, and it has been show that it is possible to prepare films with in-plane magnetization by increasing the praseodymium oxide content in the melt
