Linear tetramer formation in nonmagnetic pyrochlore niobate
Shota Nishida, Shunsuke Kitou, Shingo Toyoda +3
We investigate displacive short-range order in pyrochlore Y2Nb2O7, which exhibits a nonmagnetic insulating state despite the presence of formally tetravalent Nb4+ (S = 1/2) ions on…
Effect of uniaxial stress on helimagnetic phases in the square-lattice itinerant magnet EuAl
Masaki Gen, Takuya Nomoto, Hiraku Saito +5
We investigate uniaxial-stress effects on the magnetic phase diagram of the square-lattice itinerant magnet EuAl, where strong coupling among spin, lattice, and charge produc…
Higher-order epitaxy: A pathway to suppressing structural instability and emergent superconductivity
Yuki Sato, Soma Nagahama, Shunsuke Kitou +11
Molecular beam epitaxy enables the growth of thin film materials with novel properties and functionalities. Typically, the lattice constants of films and substrates are designed to…
Unraveling a chemical-bond-driven root of topology in three-dimensional chiral crystals
Shungo Aoyagi, Shunsuke Kitou, Yuiga Nakamura +6
Chirality manifests across multiple scales, yielding unique phenomena that break mirror symmetry. In chiral materials, unexpectedly large spin-filtering or photogalvanic effects ha…
Successive orthorhombic distortions in kagome metals by molecular orbital formation
Ryo Misawa, Shunsuke Kitou, Rinsuke Yamada +12
The kagome lattice, with its inherent frustration, hosts a plethora of exotic phenomena, including the emergence of charge density wave order. The high rotational sym…
Visualization of Co 3d high- and low-spin states via valence electron density
Kamini Gautam, Shunsuke Kitou, Yuiga Nakamura +5
Properties of trivalent cobalt oxides are governed by the spin and orbital states of Co3+ ions, which are strongly coupled to their local coordination environments and chemical bon…
Current-induced successive structural phase transitions beyond thermal equilibrium in single-crystal VO2
Shunsuke Kitou, Akitoshi Nakano, Masato Imaizumi +5
Nonequilibrium systems driven by external energy sources host unexplored physics; yet phase transitions beyond thermal equilibrium remain elusive. Here, we demonstrate that electri…
Piezoelectric Transition in a Nonpyroelectric Gyroidal Metal-Organic Framework
Shunsuke Kitou, Hajime Ishikawa, Yusuke Tokunaga +8
Among the thirty-two crystallographic point groups, 432 is the only one that lacks an inversion center but does not exhibit piezoelectricity. A gyroidal structure belongs to point…
Triangular lattice magnet GdGa with short-period spin cycloids and possible skyrmion phases
Priya R. Baral, Nguyen Duy Khanh, Masaki Gen +6
The two-dimensional triangular lattice (TAL) is a model system of magnetic frustration and competing interactions, where skyrmion spin vortices can be induced by a vertical magneti…
Ferroaxial order of the monolayer ice in martyite
Toshihiro Nomura, Shunsuke Kitou, Junichi Komatsu +13
Ice Ih, the most stable phase of water at ambient pressure, is a stacking of the honeycomb network of water molecules H2O. What if one layer of ice is exfoliated and confined to a…
Electronic Structure of Kramers Nodal-Line Semimetal YAuGe and Anomalous Hall Effect Induced by Magnetic Rare-Earth Substitution
Takashi Kurumaji, Jorge I. Facio, Natsuki Mitsuishi +11
Nodal-line semimetals are a class of topological materials hosting one dimensional lines of band degeneracy. Kramers nodal-line (KNL) metals/semimetals have recently been theoretic…
