The structural, electrical and magnetic properties of Pr0.67Ba0.22Sr0.11Mn1-xFexO3 (x = 0.00 and x = 0.05) perovskites have been investigated. All samples were prepared using solid state method and characterized by XRD, DC-AC conductivity, Magnetic, Magnetocalric measurements. The variation of conductivity with temperature shows a metal-semiconductor transition and Tc ~ 220 K, 90 K for x = 0.00 and 0.05 respectively. A paramagnetic to ferromagnetic transitions was found with decreasing temperature. The magnetocaloric effect study indicates that the investigated compounds have the appropriate properties to be suitable candidates to be used as refrigerants.
