High-temperature structural phase transition and infrared dielectric features of La2CoMnO6
R. X. Silva, A. Nonato, R. L. Moreira +2
Temperature-dependent FAR-infrared reflectivity spectra of partially ordered magnetodielectric La2CoMnO6 is presented, from room temperature up to 675 K. A clear first-ordered stru…
Short-range antiferromagnetic interaction and spin-phonon coupling in La2CoMnO6 double perovskite
R. X. Silva, C. C. Santos, H. Reichlova +3
Weak antiferromagnetic (AF) interaction in the ferromagnetic (FM) partially ordered La2CoMnO6 (LCMO) was detected by Raman spectroscopy by monitoring spin-phonon coupling. Because…
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 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.…
