### Abstract

We report measurements of thermoelectric power (TEP) for high-pressure synthesized (Formula presented)(Formula presented)(Formula presented)(Formula presented) superconductors. The magnitude of TEP for the sample with (Formula presented)=115.9 K is very small and shows a sign crossover at ∼160 K. The TEP shows a peak behavior and displays an approximately linear temperature dependence with a negative slope -0.033 μV/(Formula presented) for 120≤T≤240 K. These features resemble those for other known high-(Formula presented) cuprate superconductors, in particular (Formula presented) in the a direction for an untwinned (Formula presented)(Formula presented)(Formula presented) single crystal and polycrystalline Tl-2201 samples. A brief discussion is given on the TEP behavior in comparison with (Formula presented)(Formula presented)(Formula presented) cuprate superconductors by considering their similar structure of building blocks and type of charge reservoir.
