In present study we have studied the variation of magnetization versus applied field up to 4 T over a wide temperature range from 10 K to 70 K for Pr doped polycrystalline YBa2Cu3Ox. The critical current density has been calculated based on the magnetization measurements. Our titration measurements yielded an oxygen content of x=6.98 for the 400°C-annealed sample and x=6.62 for the 600°C-annealed sample. The electrical resistivity experiments showed transition temperature Tc. values of 91 K and 63 K for the samples annealed at 400°C and 600°C, respectively.
