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…
Incommensurate spiral order from double exchange interactions
Maria Azhar, Maxim Mostovoy
The double exchange model describing interactions of itinerant electrons with localized spins is usually used to explain ferromagnetism in metals. We show that for a variety of cry…
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…
