Correlated topological-polarization surface states in the narrow-gap insulator FeSb2
Takahiro Iwagaki, Hideki Matsuoka, Ginta Hoshino +7
Strong electron correlations and band topology each generate rich quantum phases, but conflicting elemental requirements have largely kept them apart. Topological polarization offe…
Single-crystal structural phase diagram of stoichiometric bilayer nickelate La3Ni2O7 under hydrostatic pressure
Misaki Sasaki, Zhehong Liu, Takeshi Hara +12
The study determines the pressure‑temperature phase diagram of stoichiometric La₃Ni₂O₇ single crystals, revealing a direct transition from a charge‑ordered orthorhombic Am2m struct…
Density-wave phases, anisotropic transport, and Planckian dissipation in single crystals of the superconductor La3Ni2O7
Zhehong Liu, Masamichi Nakajima, Markus Kriener +14
The study measures in‑plane and out‑of‑plane resistivities of high‑quality La₃Ni₂O₇ single crystals under pressure, revealing pressure‑tuned density‑wave phases, strong anisotropic…
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…
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…
Dominant in-plane anomalous Hall effect in a monoclinic room-temperature ferromagnet
Guoxin Zheng, Arjyama Bordoloi, Mingjun Fan +6
Ferromagnetic metals are characterized by enhanced dissipationless transverse transport responses via the anomalous Hall effect, offering a route towards magnetic sensing and spint…
