Description
We present measurements of the in-plane (κab) and out-of-plane (κc) thermal conductivity of Pr2CuO4 and Gd2CuO4 single crystals. The anisotropy gives strong evidence for a large contribution of magnetic excitations to κab, i.e. for a heat current within the CuO2 planes. However, the absolute values of κmag are lower than previous results on La2CuO4. These differences probably arise from deviations from the nominal oxygen stoichiometry. This has a drastic influence on κmag, which is shown by an investigation of a La2CuO4+δ polycrystal
