The effects of oxygen content on the superconducting transition temperatures, Tc, and magnetic properties of melt-textured LRE123 (LRE = Nd, Sm) superconductors were studied. The oxygen content could be varied by changing the annealing temperature, Ta, in that the oxygen deficiency, δ, monotonically decreased with decreasing the Ta from 600°C to 300°C. A further decrease of Ta to 275°C showed no appreciable change. In both systems the highest Tc was obtained for the samples annealed at 300°C. Magnetic properties were also strongly dependent on the oxygen content, showing that the control of oxygen content is critical for achieving good pinning properties.
