Abstract :
The films with calculated formula Lu2.1Bi0.9Fe5O12 were grown on (111) oriented GGG substrate with diameters 1, 2 and 3 inch by liquid phase epitaxy using Bi2O3-base flux. Different types of surface morphology on the grown films were observed. The films´ surface was smooth and mirror while the film thickness was less than 13 μm and becomes rough for thickness above this value. The grown films were characterized by measuring magnetization loops and magneto-optic Faraday rotation under magnetization reversal as well as ferromagnetic resonance (FMR) at 3 GHz. All films with mirror surface demonstrate the in-plane magnetization, high Faraday rotation and narrow FMR linewidth at room temperature.
