摘要：

Substitution with alkali-metals of superconducting yttrium ceramics allows varying its physical properties over a wide range The pronounced trend to hydride formation shown by these metals indicates a possibility of incorporation of superstructure hydrogen and estimation of its participation in the machanism of high-temperature superconductivity. The present paper deals with the system (Y0.86Ba1.86M0.7)Cu3OZ-y (M=K, Na, Li) and the concentration of oxygen and hydrogen in the initial powders and in the ceramics. Some peculiarities in thwe physical properties of the superconducting ceramics obtained are pointed out. © 1990 IEEE
