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
