Abstract

The perovskite-like material Sr_1.4Ta_0.6O_2.9 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.
