Spin-phonon and magnetostriction phenomena in CaMn7O12 helimagnet probed by Raman spectroscopy
A. Nonatoa, B. A. Souza, A. P. Ayala +5
In this letter we investigated the temperature-dependent Raman spectra of CaMn7O12 helimagnet from room temperature down to 10 K. The temperature dependence of the Raman mode param…
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…
