Magnetization was measured on Pr-doped YBa2Cu3O7−y for fields up to 5·5T. The paramagnetic behaviour is correlated to the free ion values of Pr3+ and Pr4+. Hysteresis experiments were done for superconducting composition for fields up to 1100 Gauss. The intragrain critical current density is calculated using Bena’s formula.
