Abstract
The crystal structure of YBa2Cu3-x Co x O7-y (x=0∼1) was investigated by X-ray and electron diffraction and the crystallographic site of Co atoms was directly determined by electron-channelling-enhanced microanalysis. It was shown that the structure is tetragonal based on the tripled perovskite structure, and that Co atoms occupy the Cu atom sites. Electric resistivity was measured with changing Co atom content and it was shown that T c did not decrease monotonically with increasing Co atom concentration.Keywords
