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…
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…
A rutile-based homologous series Na(PtO) discovered by computationally assisted high-pressure synthesis
Yasuhito Kobayashi, Hidefumi Takahashi, Shunsuke Kitou +4
Layered transition metal oxides typified by the Ruddlesden-Popper phase have been extensively studied for its applications in high-temperature superconductivity, catalysis, and bat…
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…
Entropy-assisted, long-period stacking of honeycomb layers in an AlB2-type silicide
Leonie Spitz, Takuya Nomoto, Shunsuke Kitou +8
Configurational entropy can impact crystallization processes, tipping the scales between structures of nearly equal internal energy. Using alloyed single crystals of Gd2PdSi3 in th…
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…
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…
