摘要：
The perovskite-like material Sr1.4Ta0.6O2.9 presents structural modulations due to oxygen vacancies. A non-harmonic treatment of atomic displacement parameters was used to obtain information on atom mean localization in addition to correlative displacement of cations located near oxygen vacancies.
