Abstract
The appearance of superconductivity and the relaxation of T-c to the e quilibrium value T-c approximate to 30 K in a period of five days were observed in the tetragonal ceramic NdBa2Cu3O6.67 under a pressure of 1 GPa. The superconducting phase vanishes 1.3 h after the pressure is released. This behavior is explained by the charge redistribution occu rring as a result of pressure-induced ordering of oxygen in the CuOx p lanes. (C) 1996 American Institute of Physics.
