MANA Develops Ferroelectric-ferromagnetic Materials for Next-generation Electronics| MANAPrevious Index NextResearch Highlights[Vol. 91]MANA Develops Ferroelectric-ferromagnetic Materials for Next-generationElectronics7 Jan, 2025Researchers at the Research Center for Materials Nanoarchitectonics (MANA) have proposed amethod to create ferroelectric-ferromagnetic materials, opening doors to advancing spintronicsand memory devices.In 1831, Michael Faraday discovered the fundamental connection between electricity and magnetism,demonstrating that a changing magnetic field induces electric current in a conductor.In a recent study, MANA researchers have proposed a method for designing ferroelectric-ferromagnetic(FE-FM) materials, which exhibit both ferroelectric and ferromagnetic properties, enabling themanipulation of magnetic properties using electric fields and vice versa. Such materials are highlypromising for spintronics and memory devices. The advantage of FE-FM materials, extremely rare innature, is their ability to achieve the cross-control by relatively low electric and magnetic fields. Thestudy, led by Principal Researcher Igor Solovyev from MANA, NIMS, included contributions from Dr.Ryota Ono from MANA, NIMS, and Dr. Sergey Nikolaev from the University of Osaka, Japan.Ferroelectric materials possess a permanent electric polarization, usually arising from ion displacement intheir crystalline lattice and resulting in the formation of charged electric dipoles, which align in the samedirection. The key feature of ferromagnetic materials is the uncompensated magnetic moment producedby electron spins and orbital motion. Combining both properties in a single material is challenging sincethe ion displacement enabling ferroelectricity can disrupt the magnetic ordering needed forferromagnetism. Similarly, the ferromagnetic alignment of magnetic moments is not sufficient forbreaking the spatial inversion symmetry required for producing ferroelectricity.ResearchQuantum Materials FieldNanomaterials FieldResearch SupportResearch HighlightsHot TopicsHome  > Research  > Research Highlights  > Vol. 91 MANA Develops Ferroelectric-Fe･･･About MANA Research People News Room Outreach Employment AlumniSite Map Contact Us Access to MANA Website System Requirements   Text size  Standard Large  Japanese Pagehttps://www.nims.go.jp/mana/research/highlights/vol90.htmlhttps://www.nims.go.jp/mana/research/highlights/index.htmlhttps://www.nims.go.jp/mana/research/highlights/vol92.htmlhttps://www.nims.go.jp/mana/research/index.htmlhttps://www.nims.go.jp/mana/research/quantum_material.htmlhttps://www.nims.go.jp/mana/research/nano_material.htmlhttps://www.nims.go.jp/mana/research/researcher_support.htmlhttps://www.nims.go.jp/mana/research/highlights/index.htmlhttps://www.nims.go.jp/mana/research/hottopics/index.htmlhttps://www.nims.go.jp/mana/jp/index.htmlhttps://www.nims.go.jp/mana/research/index.htmlhttps://www.nims.go.jp/mana/research/highlights/index.htmlhttp://www.jsps.go.jp/english/e-toplevel/http://www.jsps.go.jp/english/e-toplevel/https://www.nims.go.jp/mana/index.htmlhttps://www.nims.go.jp/mana/index.htmlhttps://www.nims.go.jp/mana/about/index.htmlhttps://www.nims.go.jp/mana/research/index.htmlhttps://www.nims.go.jp/mana/member/index.htmlhttps://www.nims.go.jp/mana/news_room/2024.htmlhttps://www.nims.go.jp/mana/pror/index.htmlhttps://www.nims.go.jp/mana/recruit/index.htmlhttps://www.nims.go.jp/mana/alumni/index.htmlhttps://www.nims.go.jp/mana/siteinfo/sitemap.htmlhttps://www.nims.go.jp/mana/siteinfo/inquiry.htmlhttps://www.nims.go.jp/mana/siteinfo/access.htmlhttps://www.nims.go.jp/mana/siteinfo/accessibility.htmlhttps://www.nims.go.jp/mana/jp/research/highlights/vol91.htmlThe authors of the current study proposed that antiferro orbital ordering, driven by the Kugel-Khomskiimechanism, where electrons tend to occupy alternating orbitals, can promote both ferromagneticinteractions and break the inversion symmetry. When tested on VI3, a van der Waals ferromagnet with ahoneycomb structure, this ordering resulted in an FE-FM ground state.“By properly arranging occupied atomic orbitals in a solid, one can make the material not onlyferromagnetic but also ferroelectric,” says Dr. Solovyev, highlighting the potential of this approach fordeveloping next-generation electronic devices based on multiferroic materials and ferroelectricferromagnets.ReferenceJournal Physical Review BTitle Ferromagnetic ferroelectricity due to the Kugel-Khomskii mechanism of the orbital ordering assisted byatomic Hund’s second rule effectsAuthors Igor Solovyev, Ryota Ono, S.
