Deposition of Bi-substituted iron garnet magneto-optic thin films by MOCVD

Abstract The deposition conditions for the growth of polycrystalline Bi-substituted garnet layers on glass substrates was reported. As a compromise between an efficient bismuth substitution in the films and a well uniform morphology, a 490°C deposition temperature was selected. Due to the crystallisation annealing at 600°C, the films exhibited cracks and coercivity caused by the thermal dilatation-induced stress.
