| Outline of Final Research Achievements |
The present study investigated ferroelasticity and ionic conductivity of mixed ionic-electronic conductive perovskite oxides. The present experimental and analytical results elucidated the ferroelastic mechanical behaviours of various lanthanum-based perovskite oxides such as LaCoO3-d in a wide range of temperature. Additionally, new techniques for evaluating the oxygen deficiency and ionic conductivity of these materials under uniaxial compression at elevated temperature was established. The result suggests the effect of compressive stress on the deficiency and conductivity.
