The critical current density and the irreversibility field for melt-powder-melt-growth (MPMG)-processed YBa2Cu307\_ ~ samples are determined magnetically in fields parallel to the c axis. Both Jc and Bir r are depressed with increase of oxygen deficiency. Bir r is not depressed appreciably with decr
