Dielectric magnetochiral anisotropy.
Rikken GLJA, Avarvari N. Rikken GLJA, et al. Nat Commun. 2022 Jun 22;13(1):3564. doi: 10.1038/s41467-022-31225-3. Nat Commun. 2022. PMID: 35732655 Free PMC article.
Magnetochiral anisotropy, chirality-induced spin-selectivity and helimagnetism are the most prominent phenomena resulting from this combination, touching different systems like topological (semi-)metals and insulators, quantum magnets, type II multiferroics and enantio-sel …

Magnetic Skyrmion Materials.
Tokura Y, Kanazawa N. Tokura Y, et al. Chem Rev. 2021 Mar 10;121(5):2857-2897. doi: 10.1021/acs.chemrev.0c00297. Epub 2020 Nov 8. Chem Rev. 2021. PMID: 33164494
Skyrmion, a concept originally proposed in particle physics half a century ago, can now find the most fertile field for its applicability, that is, the magnetic skyrmion realized in helimagnetic materials. The spin swirling vortex-like texture of the magnetic skyrmion can …

Helimagnetism of Fe: high pressure study of an Y2Fe17 single crystal.
Prokhnenko O, Kamarád J, Prokes K, Arnold Z, Andreev AV. Prokhnenko O, et al. Phys Rev Lett. 2005 Mar 18;94(10):107201. doi: 10.1103/PhysRevLett.94.107201. Epub 2005 Mar 15. Phys Rev Lett. 2005. PMID: 15783514
In this Letter we present direct observation of the Fe helimagnetism in an Y2Fe17 single crystal under pressure. Combined neutron diffraction and magnetization measurements under pressure showed that the collinear ferromagnetic phase of Y2Fe17 is substituted by the pressur …

Curvilinear One-Dimensional Antiferromagnets.
Pylypovskyi OV, Kononenko DY, Yershov KV, Rößler UK, Tomilo AV, Fassbender J, van den Brink J, Makarov D, Sheka DD. Pylypovskyi OV, et al. Nano Lett. 2020 Nov 11;20(11):8157-8162. doi: 10.1021/acs.nanolett.0c03246. Epub 2020 Oct 20. Nano Lett. 2020. PMID: 32986440
We show that an intrinsically achiral one-dimensional (1D) curvilinear antiferromagnet behaves as a chiral helimagnet with geometrically tunable Dzyaloshinskii-Moriya interaction (DMI) and orientation of the Neel vector. ...

Emergent electromagnetic induction beyond room temperature.
Kitaori A, Kanazawa N, Yokouchi T, Kagawa F, Nagaosa N, Tokura Y. Kitaori A, et al. Proc Natl Acad Sci U S A. 2021 Aug 17;118(33):e2105422118. doi: 10.1073/pnas.2105422118. Proc Natl Acad Sci U S A. 2021. PMID: 34389677 Free PMC article.
We report here large emergent electromagnetic induction achieved around and above room temperature, making use of a few tens of micrometer-sized devices based on the high-temperature (up to 330 K) and short-period ( 3 nm) spin-spiral states of a metallic helimagnet. The ob …
