Abstract

The local structure of YBa2Cu408 doped with Ca was studied by extended X-ray absorption fine structure (EXAFS) analysis. X-ray absorption measurements at the Ca X-edge indicate that Ca2+ ions substitute for Y3+ ions and are coordinated to eight oxide ions with a Ca —O distance of about 2.37 A. The local structures around Ba and Cu atoms are also reported.
