We report synthesis of rare earth manganite samples with co-substitution of divalent Ca at La site and magnetic Fe at Mn site. The lattice structure remained unaffected with 5% and 10% substitution of Fe. However, the charge transport had profound effect of this substitution. The metal-insulator transition temperature lowered from 270 K to 200 K for 5% substitution. It also resulted in widening of transition width and the magnetoresistance value over 50% was sustained over a temperature range more than 225 K. The broad transition was also confirmed through magnetic measurement.
