Abstract

Chemical Equation Presentation Extended X-ray absorption fine structure spectroscopy (EXAFS) was used to determine the interatomic distances in both strain-free and strained thin films of Ce_0.8Cd_0.2O _1.9. It was found that in response to compressive strain, the Ce ⁴⁺ ion undergoes an anomalously large shift away from the oxygen vacancy. This finding offers a microscopic explanation for the elastic anomalies observed in Ce_0.8Gd_0.2O_1.9.
