Abstract :
The (BiSmLuCa)3(FeSi)5O12 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 Lu2O3/Sm2O3 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
