Magnetoelastic mapping of the high-field phase diagram in the topological cubic helimagnet SrFeO
Masaki Gen, Shun Okumura, Shusaku Imajo +9
The cubic perovskite SrFeO is a prototypical centrosymmetric itinerant magnet that hosts a quadruple- hedgehog-antihedgehog lattice and exhibits a complex magnet…
Collinear ferromagnetism with reduced moment length in kagome magnet Nd3Ru4Al12
Yuki Ishihara, Ryota Nakano, Rinsuke Yamada +14
We determine the magnetic ground state of the kagome lattice magnet Nd3Ru4Al12 by single-crystal neutron diffraction, supported by experiments with polarized neutrons. We identify…
Frustration of harmonic and solitonic helimagnetism on the body-centered tetragonal lattice of GdAlSi
Ryota Nakano, Rinsuke Yamada, Oleg I. Utesov +9
The triangular lattice antiferromagnet (TLAF) with nearest-neighbor exchange interaction is a model platform in the field of frustrated magnetism. Here, anharmonic (`up-up-down') a…
Real-space determination of orbital states driving successive phase transitions in FeV2O4
Chihaya Koyama, Yusuke Nomura, Shunsuke Kitou +8
Direct experimental access to orbital states in strongly correlated materials remains a major challenge, despite their central role in driving coupled structural and magnetic phase…
Experimental quantification of electronic symmetry breaking through orbital hybridization phase
Shungo Aoyagi, Shunsuke Kitou, Yuiga Nakamura +2
Symmetry classification of crystal structures has been central to predicting physical properties of materials. While such structural classification identifies which physical respon…
Bond-density-wave orders induced by geometric frustration in the kagome metal CeRu3Si2
Ryo Misawa, Shunsuke Kitou, Rinsuke Yamada +9
Geometric frustration gives rise to vast manifolds of degenerate ground states and competing orders in spin and charge systems. Typically, classical ground states are governed by a…
Magnetoelectric Control of Toroidal Moment in Ferroaxial Crystal PbMnNiTeO
Shungo Aoyagi, Shunsuke Kitou, Taka-hisa Arima +1
Ferroic multipole orders break some symmetry and often activate unique physical properties, such as nonreciprocal directional dichroism and linear magnetoelectric effects. Here, we…
Skyrmion and Meron Crystals in Intermetallic GdRuAl: Microscopic Model Insights into Chiral Phases
Jiajun Mo, Leandro M. Chinellato, Fletcher Williams +14
Topological spin textures in frustrated intermetallics hold great promise for spintronics applications. However, understanding their origin and properties remains a significant cha…
Low energy excitations in A-site ordered SmBaMn2O6
Mirian Garcia Fernandez, Abhishek Nag, Stefano Agrestini +5
The electron in a solid can be considered a bound state of the three independent, fundamental degrees of freedom creating quasi-particles: spinons, carrying the electron spin; plas…
Perfectly harmonic spin cycloid and multi- textures in the Weyl semimetal GdAlSi
Ryota Nakano, Rinsuke Yamada, Juba Bouaziz +18
A fundamental question concerns how topological electronic states are influenced by many-body correlations, and magnetic Weyl semimetals represent an important material platform to…
Metallic -wave magnet with commensurate spin helix
Rinsuke Yamada, Max T. Birch, Priya R. Baral +20
Antiferromagnetic states with spin-split electronic structure give rise to novel spintronic, magnonic, and electronic phenomena despite (near-) zero net magnetization. The simplest…
Visualization of spin-orbit entangled 4f electrons in crystalline materials
Shunsuke Kitou, Kentaro Ueda, Yuiga Nakamura +5
Lanthanide 4f electrons are strongly influenced by spin-orbit coupling, resulting in well-defined J multiplets, which are further split by the crystalline electric field in condens…
Giant Hall effect in a highly conductive frustrated magnet GdCu
Kosuke Karube, Yoshichika Ōnuki, Taro Nakajima +10
The Hall effect is one of the most fundamental but elusive phenomena in condensed matter physics due to the rich variety of underlying mechanisms. Here we report an exceptionally l…
