The Tc of Nd 1÷xBa2\_xCuaOy (0.1 ~<x~ 0.6) has been increased by synthesizing and annealing the compounds in 200 bar oxygen pressure. The oxygen content, y, increases to compensate the effect of Nd a+ substitution and the formal average copper valence (FACV) remains unchanged at ~ 2.3 throughout the
