Title: Structure and transport properties in YBa{sub 2-x}Eu{sub x}Cu{sub 3}O{sub 7-{delta}} superconductors

Abstract

Structure and transport properties of Eu-doped YBa{sub 2-x}Eu{sub x}Cu{sub 3}O{sub 7-{delta}} (YBECO) have been studied. Eu is confirmed preferring to replace Ba at Ba sites. The averaged valence state of Eu, which is examined by x-ray photoemission spectroscopy, increases with increasing x. Eu doping in YBECO has a little influence on superconductivity in our studies, and the superconducting transition temperature T{sub c} is almost unchanged.
