摘要：

We have made AC susceptibility measurements from 4.2 to 100K on two different types of single crystals of yttrium barium copper oxide (Y1Ba2Cu3O7-δ) as a function of oxygen concentration. In both cases as Tc is reduced by oxygen depletion a small T2 term in the low temperature diamagnetic response grows systematically. It follows a similar trend with Tc as does the c-axis resistivity. This, and other evidence indicate that it corresponds to a small T2 term in λc(T) the largest component of the penetration depth tensor. © 1990.
