Abstract

We have been investigating the possibility that the presence or absence of hydrogen may influence the electrical properties of the high TQ superconductor YBa2Cu3O7−x. Samples were prepared sintering in wet and dry oxygen, ana have been loaded by exposure to a plasma discharge of hydrogen gas. The hydrogen concentration near the surface was monitored by the H(15N, αγ) C reaction, and the four point method was used for the electrical measurements. The tentative results are that hydrogen content has little effect on either the transition temperature or the sharpness of the transition, although higher concentration may increase the normal state resistivity.
