Description
The oxygen isotope effect was studied in the system (Y1-xPrx)Ba2Cu3O7-δ for x=0.2, 0.3, 0.4, and 0.5. It is found that the oxygen isotope exponent α increases with increasing x and therefore decreasing transition temperature Tc. For the highest Pr concentrations α tends toward α=0.5. The value of the isotope exponent depends on the concentration of mobile holes. The lower this concentration is, the larger becomes the isotope exponent
