Abstract
  • The effect of oxygen vacancies on the elastic properties of BaCe0.9Y0.1O3−d is studied by measuring the complex Young's modulus between 80 and 850 K varying the content of O vacancies from 0 to nearly 0.05. The Young's modulus measured at a fixed temperature above 300 K may change by more than 20% but this is due to a shift of the rhombohedral-orthorhombic transition by 250 K and to proton and vacancy hopping. Below 100 K these effects are frozen and the filling of the O vacancies with OH ions increases the Young's modulus by ~1.3% (literal)
