Fate of Pomeranchuk effect in ultrahigh magnetic fields
Naofumi Matsuyama, So Yokomori, Toshihiro Nomura +8
The Pomeranchuk effect is a counterintuitive phenomenon where liquid helium-3 (3He) solidifies under specific pressures, not when cooled, but when heated. This behaviour originates…
Anomalous Electrical Transport in the Kagome Magnet YbFeGe
Weiliang Yao, Supeng Liu, Hodaka Kikuchi +19
Two-dimensional (2D) kagome metals offer a unique platform for exploring electron correlation phenomena derived from quantum many-body effects. Here, we report a combined study of…
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…
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…
= 1/2 Hyperoctagon Lattice in Cobalt Oxalate Metal-Organic-Framework
Hajime Ishikawa, Shusaku Imajo, Hikaru Takeda +4
We report the magnetic properties of a cobalt oxalate metal-organic-framework featuring the hyperoctagon lattice. Our thermodynamic measurements reveal the = 1/2 sta…
Geometric frustration and Dzyaloshinskii-Moriya interactions in a quantum star lattice hybrid copper sulfate
Hajime Ishikawa, Yuto Ishii, Takeshi Yajima +6
We study the magnetism of a layered, spin- organic-inorganic copper sulfate, which is a close realization of the star lattice antiferromagnet, one of the playgrounds of ge…
Kitaev Spin Liquid Candidate OsxCl3 Comprised of Honeycomb Nano-Domains
K. Kataoka, D. Hirai, T. Yajima +11
An osmium chloride with the chemical formula of OsxCl3 (x = 0.81) was synthesized and its crystal structure and thermodynamic properties were investigated. OsxCl3 crystallizes in a…
Ordering of hidden multipoles in spin-orbital entangled 5 Ta chlorides
Hajime Ishikawa, Tomohiro Takayama, Reinhard K. Kremer +5
Spin-orbit coupling of as large as a half eV for electrons in 5 orbitals often gives rise to the formation of spin-orbital entangled objects, characterized by the effective tota…
