Paper Abstract

Bi-substitued garnet films with large Faraday rotation and saturation magnetization, low microwave losses and planar anisotropy for a low in-plane saturation field requirement in integrated optics have been investigated. For such a purpose three material composition sets with increasing Bi contents have been grown from L.P.E. on (111)- and (110)- oriented GGG substrates and their magnetic properties analyzed before and after heat treatment under different annealing temperature. Well defined quenching temperatures can be adjusted to obtain either perpendicular or in-plane easy axis or intermediate structure useful for magnetooptical waveguide devices with optimized Faraday or Cotton-Mouton geometry.
