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
