Ordering effect on the electrical properties of stoichiometric Ba${}_3$CaNb${}_2$O${}_9$-based perovskite ceramics

J. E. Rodrigues, D. M. Bezerra, A. C. Hernandes

Cation ordering is most common process detected in A${}_3$B'B"${}_2$O${}_9$-based complex perovskites. Some important physical features of this system are due to the B-site orderin…
