摘要：

We calculate the penetration depth T for a model of the high- Tc superconductors based upon proximity coupling between one superconducting S and one normal N layer per unit cell. The linear, low- T region of the abT data of Bonn et al. on YBa2Cu3O7- is fitted quantitatively for both s-wave and dx2-y2 order parameters. However, these fitted models give very different predictions for cT, which may serve as a new test for the order parameter, or at least for the role of N layers. © 1995 The American Physical Society.
