Crystal Growth and Characterization of the Rare-earth Orthoferrite Sm$lt;inf$gt;0.8$lt;/inf$gt;Tb$lt;inf$gt;0.2$lt;/inf$gt;FeO$lt;inf$gt;3$lt;/inf$gt; Single Crystal

Sm 0.8 Tb 0.2 FeO 3 single crystal was grown by the floating zone method. Laue back reflection was used to check the crystal's quality and orientation. The temperature dependence of the magnetization under ZFC process was measured in an external field 500 Oe along c-axis. A clear spin reorientation is observed in the range of 360-400 K.
