Space Group Symmetry of BaFeSe: ab initio-Experiment Phonon Study
M. J. Weseloh, V. Balédent, W. Zheng +7
This paper presents a study of the structure dynamics in BaFeSe. We combined first-principle calculations, infrared measurements and a thorough symmetry analysis. Our study…
Multiferroicity and magnetoelastic coupling in alpha-Mn2O3: A binary perovskite
Mohit Chandra, Satish Yadav, R. J. Choudhary +4
Multiferroics where at least two primary ferroic orders are present and coupled in a single system constitute an important class of materials. They attracted special consideration…
Can we prevent the "dead layer" formation at manganite interfaces?
Ayşegül Begüm Koçak, Julien Varignon, Sébastien Lemal +2
The present work theoretically studies the possibility to hinder the formation of a "dead" layer at the interfaces in manganite superlattices. We showed that this goal can be reach…
First principles calculation of the phonons modes in the hexagonal ferroelectric and paraelectric phases
Julien Varignon, Sébastien Petit, Marie-Bernadette Lepetit
The lattice dynamics of the magneto-electric compound has been investigated using density functional calculations, both in the ferroelectric and the paraelectric phase…
Constrained ferroelectric domain orientation in (BiFeO3)m(SrTiO3)n superlattice
R. Ranjith, R. V. K. Mangalam, Ph. Boullay +10
Ferroelectric domains were investigated using piezoresponse force microscopy in superlattices composed of multiferroic BiFeO3 and SrTiO3 layers. Compared to single BiFeO3 thin film…
Elastic and magnetic effects on the infrared phonon spectra of MnF2
R. Schleck, Y. Nahas, R. P. S. M. Lobo +4
We measured the temperature dependent infrared reflectivity spectra of MnF2 between 4 K and room temperature. We show that the phonon spectrum undergoes a strong renormalization at…
