Ordering effect on the electrical properties of stoichiometric BaCaNbO-based perovskite ceramics
J. E. Rodrigues, D. M. Bezerra, A. C. Hernandes
Cation ordering is most common process detected in AB'B"O-based complex perovskites. Some important physical features of this system are due to the B-site orderin…
Raman signatures of monoclinic distortion in (BaSr)CaNbO complex perovskites
J. E. Rodrigues, D. M. Bezerra, R. C. Costa +2
Octahedral tilting is most common distortion process observed in centrosymmetric perovskite compounds (ABO). Indeed, crucial physical properties of this oxide stem from the t…
Synthesis and structural ordering of nano-sized Ba3B'Nb2O9 (B'= Ca and Zn) powders
João Elias Figueiredo Soares Rodrigues, Débora Morais Bezerra, Adeilton Pereira Maciel +1
In this work we investigated the phase formation and structural ordering of BaBNbO (B Ca and Zn) perovskite powders obtained by a modified polymer…
Ordering and phonons in BaCaNbO complex perovskite
João Elias Figueiredo Soares Rodrigues, Edvan Moreira, Débora Morais Bezerra +2
In this work we performed a detailed investigation about ordering in \bcn perovskite. The sintering temperature and time were changed to obtain samples with different ordering. The…
Ba(Zn1/3Nb2/3)O3 thin films obtained by polymeric precursors method
João Elias Figueiredo Soares Rodrigues, Débora Morais Bezerra, Adeilton Pereira Maciel +2
In this work Ba(Zn1/3Nb2/3)O3_3$ thin films were prepared by the polymeric precursors method. A detailed description of the procedure to obtain the precursors and deposition was pr…
