We have performed electrical resistivity and DC magnetization measurements as a function of temperature, on polycrystalline samples of phase-separated La 5/8Γy Pr y Ca 3/8 MnO 3 (y ΒΌ 0.3). We have used the general effective medium theory to obtain theoretical resistivity vs. temperature curves corre
