Abstract

In the present work we report structural, electrical, magnetic and thermo-power of Pr_0.8-xDy_xSr_0.2MnO₃ with (x = 0, 0.2 and 0.25) manganites. It is observed that Curie temperature T_C decreases with Dy doping and also ZFC magnetization curves decrease more sharply with Dy from magnetization study. Though, Dy³⁺ ion has large magnetic moment μ = 10.65μ_B, because of its smaller ionic radius that of Pr³⁺ ion, changes in magnetic properties have observed. The zero field resistivity for pristine sample shows a small peak at around 157 K, near the metal-insulator transition temperature (T_MI), which is also closer to the Curie temperature T_C and a more pronounced peak at (T_f) around 95 K. All samples show the positive thermo-electric power throughout the temperature range.
