摘要：

We report detailed results on the complex conductivity of YBCO powder at 5GHz, including the normal state conductivity, critical point behaviour, abnormal behaviour at low temperatures and departures from BCS theory at intermediate temperatures. We also discuss a size dependence in our results which may be associated with the removal of defects in the grinding process. © 1990, Elsevier Science Publishers B.V. (North-Holland).
