%X In this work, we present photoconductivity measurements performed on metallic p-type Pb1-xEuxTe epitaxial films for x similar to 0.02 and x similar to 0.03 in the temperature range of 77K-300 K. The results show that sample with x similar to 0.02 presented negative photoconductivity effect in the whole range of temperatures measured, while sample with x similar to 0.03 presented a transition from positive to negative photoconductivity. Hall measurements were also performed to investigate the effects observed in both samples, but could not give any conclusive explanation. On the other hand, we showed that disorder changes considerably the generation/recombination ratios as temperature is varied giving rise to the anomalous effects observed.
