Abstract
We have examined the relationship between in-plane orientation, grain size, fluctuation of grain axis and surface resistance of YBa2Cu3O7-delta (YBCO) films. The surface resistance of YBCO films with a mixture of (100) and (1 10) in-plane grains was larger than that of the films with perfect in-plane orientation. The behavior of surface resistance could be explained by the degree of grain boundaries of (100) and (110) in-plane orientation. The sur face resistance of YBCO films was proportion to the fluctuation of grain ax is. It was also proven that surface resistance of high-temperature supercon ductors is affected by the critical current.
