摘要：
A non-resonant microwave absorption technique is used to study the magnetic shielding effects in Ag-doped and pure YBa2Cu3O7-x (YBCO) thin films for small modulating fields. While Ag-doped YBCO thin films show good shielding for small modulating fields (approximate to 1 Oe) until 60 K, the pure YBCO films show significant shielding effect only up to 20 K. We interpret these results in terms of better grain alignment in Ag-doped YBCO films as compared to pure YBCO films, which can lead to better shielding effects. (C) 1997 Elsevier Science Ltd.
