Abstract
Previous studies have shown that when hydrogen is added to the superconductor YBa2Cu3O7 (O7), it affects many of its properties, as if chain oxygen were removed. Hence the effect of H on the material should be quite different when these oxygen atoms are missing. We have therefore studied the influence of H on YBa2Cu3O6 (O6). In contrast to the case of O7, the 89Y NMR resonance frequency is independent of x; instead a second line evolves that is shifted to a higher frequency with respect to the original line. The results confirm that hydrogen in O6 qualitatively plays a different role than hydrogen in O7. The quadrupole interaction of 2H in the material yields a coupling constant e2qQ h of about 250 kHz which indicates that the hydrogen forms an O-H bond. X-ray diffraction results are also discussed.
