Here we examine the dependence of the thermal conductivity, K, of La0.67Ca0.33MnO3+/-{\\delta} as a function of density, grain size and silver impregnation around room temperature. We use a simple effective medium model to extract relevant trends in the data and demonstrate a threefold increase in thermal conductivity by silver impregnation.","authors_text":"A. Berenov, J. A.
