Abstract

High-precision thermal conductivity measurements have been performed on a single crystal of La_1.67Sr_0.33NiO₄ as well as on polycrystalline samples of La_2-xSr_xNiO₄(x = 0.33, 1) and Sr_1.5La_0.5MnO₄. The charge/spin stripe order in La_1.67Sr_0.33NiO₄ and Sr_1.5La_0.5MnO₄ leads to a straightforward interpretation of our results in terms of static and dynamic stripe correlations. Polarons may play a major role in the metallic compound of LaSrNiO₄. These results corroborate a recent thermal conductivity study of rare earth doped La_2-xSr_xCuO₄ which reveals the possible importance of dynamic stripe correlations on cuprate superconductivity.
