英文摘要	SmFeO3ceramic balls were prepared via containerless aerodynamic levitation, their microstructure and magnetic properties were investigated. The spherical surface of SmFeO3is a unique structure of the blend of dendritic and precipitates. The solidification process of the sphere is from the surface to the inside, finally forming the "orange crystal". Similar to the single crystal, SmFeO3ceramic balls show nearly rectangular hysteresis loops at room temperature, which favors the improvement of the response speed of magneto-optical switch. The spin orientation temperature and the Neel temperature both are above the room temperature at an external magnetic field of 159×103A/m. The magnetic torque of SmFeO3begins to gradually reduce at 140 K, and decreases sharply as the temperature reduces to 40 K, which is attributed to the spin activation of the reverse parallel Sm3+ions. © 2017, Editorial Department of Journal of the Chinese Ceramic Society.
