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…
Spiral order from orientationally correlated random bonds in classical XY models
Andrea Scaramucci, Hiroshi Shinaoka, Maxim V. Mostovoy +3
We discuss the stability of ferromagnetic long-range order in three-dimensional classical XY ferromagnets upon substitution of a small subset of equally oriented bonds by impurity…
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…
Incommensurate magnetic structure, Fe/Cu chemical disorder and magnetic interactions in the high-temperature multiferroic YBaCuFeO5
M. Morin, A. Scaramucci, M. Bartkowiak +9
Motivated by the recent observations of incommensurate magnetic order and electric polarization in YBaCuFeO5 up to temperatures TN2 as high as 230K [1,2] we report here for the fir…
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…
