Intrinsic dielectric properties of magnetodielectric LaCoMnO
R. X. Silva, R. L. Moreira, R. M. Almeida +2
Manganites with double perovskite structure are being attractive because of their interesting magnetoelectric and dielectric responses. Particularly, colossal dielectric constant (…
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…
Spin-phonon coupling in BaFe12O19 M-type hexaferrite
Flávio M. Silva Júnior, Carlos W. A. Paschoal
The spin-phonon coupling in magnetic materials is due to the modulation of the exchange integral by lattice vibrations. BaFe12O19 M-type hexaferrite, which is the most used magneti…
Mechanism of luminescent enhancement in Ba2GdNbO6:Eu3+ perovskite by Li+ co-doping
Marcos Vinicius dos Santos Rezende, Mario Ernesto Giroldo Valério, Rodolpho Mouta +2
We investigated the Li+ ion incorporation in Ba2GdNbO6:Eu3+ perovskite by atomistic simulations based on energy minimization. We predicted the most probable sites occupied by Eu3+…
Spin-phonon coupling in Gd(Co1/2Mn1/2)O3 perovskite
R. X. Silva, H. Reichlova, X. Marti +4
We have investigated the temperature-dependent Raman-active phonons and the magnetic properties of Gd(Co1/2Mn1/2)O3 perovskite ceramics in the temperature range from 40 K to 300 K.…
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…
