The effect of Pr ion concentration on superconducting parameters in Y1−xPrxBa2Cu3O7−δ single crystals

Abstract Y 1− x Pr x Ba 2 Cu 3 O 7−δ single crystals with x = 0.1, 0.2 and 0.3 were grown by the flux method. We analyzed the reversible magnetization with the external field parallel to the c-axis and obtained the various thermodynamic parameters using the Hao-Clem model. Comparing thermodynamic parameters of pure YBa 2 Cu 3 O 7−δ , we discussed the effect of Pr ion on the superconducting properties.
