Abstract
Specific heat, magnetic susceptibility and magnetoresistivity measurements have been performed on the polycrystalline samples of Fe-substituted manganites. The transition temperatures derived from the specific heat anomalies for x=0,0.01,0.06 were in agreement with the position of the maximum slope of AC susceptibility. For compositions with x=0.10 and 0.15 no transition was observed in the specific heat. A sharp increase in resistivity below 135 and 125K was observed in zero field for x=0.10, and 0.15, respectively.
