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…
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…
Exploration of metastable A-site-ordered perovskites (Ca,Ba)FeO3-δ by computationally-guided multi-step synthesis
Masaho Onose, Hidefumi Takahashi, Hajime Sagayama +2
Perovskite-type iron oxides with Fe4+ ions have attracted much attention for their versatile helimagnetic phases. While the introduction of a layered A-site ordered structure to AF…
Mass enhancement and metal-nonmetal transition driven by d-f hybridization in perovskites La1-xPrxCuO3
H. Takahashi, M. Ito, J. Fujioka +6
We report the large electron-mass enhancement and the metal to nonmetal transition upon the Pr doping in perovskite-type La1-xPrxCuO3. With increasing the Pr content x around 0.6,…
Topological Semimetal KAlGe with Novel Electronic Instability
Toshiya Ikenobe, Takahiro Yamada, Jun-ichi Yamaura +6
Compounds with the anti-PbFCl structure exhibit a variety of electronic instabilities and intriguing physical properties. NaAlSi and NaAlGe are similar topological nodal-line semim…
