Abstract

The effects of Nd 3+ and Lu 3+ ions in garnet LPE films are investigated on magnetic and magnetooptic properties. The magnetization and FMR measurements show in-plane anisotropy for both films. Faraday rotation is remarkably enhanced as the content of Nd 3+ ions increases. The anisotropy and Faraday rotation of LuNd-IG film are slightly larger than those of YNd-IG one. This suggests the difference of Nd-segregation coefficient between both systems.
