Key role of local structure in the anomalous superconductivity of the Ce1−La Ru2 system
Source abstract
Abstract
Abstract We report Ru K-edge extended X-ray absorption fine structure (EXAFS) measurements on the Ce1−xLaxRu2 superconducting system with variable La concentration. The correlated Debye–Waller factor of the Ru–Ru bonds follows the Tc of the system. This remarkable Tc dependence indicates the key role of local atomic displacements in the anomalous superconductivity of the system at small La concentration.
