Magnetic order in 4-layered Aurivillius Phases
Axiel Yaël Birenbaum, Andrea Scaramucci, Claude Ederer
We determine the viability of 4-layered Aurivillius phases to exhibit long-range magnetic order above room temperature. We use Monte Carlo simulations to calculate transition tempe…
Multiferroic magnetic spirals induced by random magnetic exchanges
Andrea Scaramucci, Hiroshi Shinaoka, Maxim V. Mostovoy +4
Multiferroism can originate from the breaking of inversion symmetry caused by magnetic-spiral order. The usual mechanism for stabilizing a magnetic spiral is competition between ma…
Strain-Induced Magnetic Anisotropy in Epitaxial Thin Films of the Spinel CoCrO
Jeroen A. Heuver, Andrea Scaramucci, Yves Blickenstorfer +4
We show that the magnetic anisotropy in spinel-structure CoCrO thin films exhibits a strain dependence in which compressive strain induces an out-of-plane magnetic easy axi…
Biquadratic and ring exchange interactions in orthorhombic perovskite manganites
Natalya S. Fedorova, Claude Ederer, Nicola A. Spaldin +1
We use ab initio electronic structure calculations within the generalized gradient approximation (GGA+U) to density functional theory (DFT) to determine the microscopic exchange in…
On the calculation of crystal field parameters using Wannier functions
Andrea Scaramucci, Jens Ammann, Nicola A. Spaldin +1
We discuss the calculation of crystal field splittings using Wannier functions and show how the ligand field contributions can be separated from the bare Coulomb contribution to th…
Linear Magnetoelectric Effect by Orbital Magnetism
Andrea Scaramucci, Eric Bousquet, Michael Fechner +2
We use symmetry analysis and first principles calculations to show that the linear magnetoelectric effect can originate from the response of orbital magnetic moments to the polar d…
