Influence of growth conditions on anisotropy energy coefficients for samarium doped garnet films

The (BiSmLuCa)/sub 3/(FeSi)/sub 5/O/sub 12/ composition has been investigated using step-by-step experiments on growth conditions in order to find a way to control uniaxial anisotropy. The effects of a supercooling, saturation temperature, and Lu/sub 2/O/sub 3//Sm/sub 2/O/sub 3/ molar ratio have been demonstrated. Relationships between composition and growth conditions were obtained using data for anisotropy. Based on these results, the authors have obtained an empirical formula for growth-induced anisotropy that can be expressed according to Hibiya's model by a modified relation.<
