Structural and magnetization dynamic properties of Bi0.1Y2.9Fe5O12(BYIG) thin film grown over single crystalline Gadolinium gallium garnet (GGG, [111]& [100]) substrate by excimer pulsed laser deposition (PLD) are reported. X-ray diffraction and Ferromagnetic resonance(FMR) have been performed on in-situ annealed film.BYIG over GGG with [100] is grown structurally better than film grown over GGG having [111] plane. It has a very narrow FMR line width (23.50 Gauss) compared with film grown over GGG ([111]) (51.60 Gauss) and BYIG thin film grown over GGG with [100] orientationhave very low Gilbert damping constant (1.42×10-5) as compared with film grown over GGG with [111] orientation(2.5×10-4). Bi-doped YIG thin film grown on GGG [100] substrate shows very low damping and hence can be used for microwave devices such as micro wave filter etc. |
