In the present investigation structural, magneto-transport, magnetic and thermo-power measurements of Gadolinium (Gd) doped Pr0.8-xGdxSr0.2MnO3 (0, 0.2, 0.25 and 0.3) manganites have been done. All the samples are single phased with orthorhombic structure. Temperature variation of resistance exhibits a high temperature transition occurring at 156 K and a low temperature cusp at around 95 K for pristine sample. With Gd doping resistance behavior shows insulating behavior throughout the whole temperature range. Magneto-Resistance (MR%) increases with Gd doping. A huge increase in thermo-electric power is observed with Gd doping.
