N2 - Structural, electrical and magnetic properties of Pr0.7-xBi xSr0.3MnO3 (x = 0.00, 0.15, 0.25) compound have been studied. A decrease in unit cell volume is observed, although Bi 3+ (1.17 ) ion has larger ionic radii than Pr3+ (1.126 ) ion and can be understood in a scenario of coexistence of charge ordered and ferromagnetic phase. "Electrical-resistivity and Magnetic" measurements show that the transition temperature (TMI, T C) increases i.e. "284.6 K, 276.5 K" to "294.04 K, ∼300 K" for Pr0.70Sr0.3MnO3 and Pr0.45Bi0.25Sr0.3MnO3 compounds, respectively. Larger ionic size of Bi3+ ion encourages double-exchange (DE) interaction, which in turns result an increase in transition temperatures.
