Abstract The results of thermopower measurements in a high J_c melt-textured growth (MTG) YBa₂ Cu₃ O₇ bulk sample above 80K are reported, its behavior is strongly anisotropic. The small value in c-direction indicates the existence of an imperfection in the alignment of ab-planes and low resistance channels along the c-axis, which may be important for the high J_c value of the sample. Described by a two order tensor, the orientational dependence of thermopower can also be explained.
