  We have performed electrical resistivity and DC magnetization measurements as
a function of temperature, on polycrystalline samples of phase separated
LaPrCaMnO. We have used the General Effective Medium Theory to obtain
theoretical resistivity vs. temperature curves corresponding to different fixed
ferromagnetic volume fraction values, assuming that the sample is a mixture of
typical metallic like and insulating manganites. By comparing this data with
our experimental resistivity curves we have obtained the relative ferromagnetic
volume fraction of our sample as a function of temperature. This result matches
with the corresponding magnetization data in excellent agreement, showing that
a mixed phase scenario is the key element to explain both the magnetic and
transport properties in the present compound.
