Abstract

In this work, Sm0.3Tb0.7FeO3 single crystal was successfully grown by optical floating zone method. Sm0.3Tb0.7FeO3 samples with a-, b-, and c-orientation were manufactured by means of Laue photograph. Magnetic properties of Sm0.3Tb0.7FeO3 single crystals are studied over a wide temperature range from 2 to 400K. Spin reorientation transition from Γ2 to Γ4 are observed by means of the temperature dependence of magnetization It indicated the reorientation transition temperature of Sm1−xTbxFeO3 single crystals is lowered with the contents of Tb contents rising based on this work and our previous works, thus the spin reorientation transition temperature can be adjusted through changing the compound in orthoferrites materials, which means that we can get orthoferrites single crystals with high magnetism property in various temperature through material design.
