Transport properties of Eu-doped La_2−xSr_xCuO₄ — •E. Ahmed¹, C. Hess¹, B. Büchner¹, U. Ammerahl², and A. Revcolevschi² — ¹II. Physikalisches Institut, RWTH-Aachen, D-52056 Aachen — ²Laboratoire de Physico-Chimie des Solides, Université Paris-Sud, 91405 Orsay Cedex, France

We present measurements of resistivity, thermopower, thermal conductivity and the Hall coefficient of Eu-doped La_2−xSr_xCuO₄ single crystals. All quantities exhibit pronounced anomalies in the low temperature tetragonal phase (LTT-phase). We discuss the importance of stripe correlations for these observations.
