An ab initio study of magneto-electric coupling of
J. Varignon, S. Petit, A. Gellé +1
The present paper proposes the direct calculation of the microscopic contributions to the magneto-electric coupling, using ab initio methods. The electrostrictive and the Dzyaloshi…
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…
Tailoring non-collinear magnetism and 3d 4f exchange interactions in RVO epitaxial thin films
O. Copie, J. Varignon, I. C. Infante +8
In orthorhombic perovskite oxides (RMO), substituting R rare-earth cations tailors the spin, orbital, and charge degrees of freedom of the central M transition me…
Nanoscale characterization of atomic positions in orthorhombic perovskite thin films
M. Martirosyan, S. Passuti, G. Masset +12
The crystal structure determines many of the physical properties of oxide perovskites (ABO) and only a tiny modification of the lattice structure causes major changes in the fu…
Growth orientation and magnetic properties of GdVO tailored by epitaxial strain engineering
M. Martirosyan, A. Gudima, J. Varignon +5
Transition-metal oxides with an ABO perovskite structure exhibit significant coupling between spin, orbital, and lattice degrees of freedom, highlighting the crucial role of la…
Hybridization-controlled charge transfer and induced magnetism at correlated oxide interfaces
M. N. Grisolia, J. Varignon, G. Sanchez-Santolino +11
At interfaces between conventional materials, band bending and alignment are classically controlled by differences in electrochemical potential. Applying this concept to oxides in…
