Magnetization Plateau and Spin Supersolidity in YCu(OD)Br under Magnetic Fields up to 120~T

Hiroaki Hayashi, Han Li, Feng-Feng Song +11

We performed high-precision magnetization measurements up to 120~T on three compositions of the newly discovered kagome antiferromagnet YCu(OD)Br (YCOB), reveal…

Non-linear diffusion and inhomogeneity of the magnetic field in single-turn coils: Insights from 3D multiphysics modeling

Hideaki Kobayashi, Yugaku Goyo, Yuto Ishii +3

The single-turn coil method is a destructive pulsed magnet for generating over 100 T with a few -second pulse duration, and it inevitably causes the coil to explode. The tempora…

Efficiency in a repetitive pulse magnet

Akihiko Ikeda, Yuto Ishii, Yasuhiro H. Matsuda +3

A repetitive-pulse magnet is a promising tool when combined with repetitive excitations, such as pulsed lasers. Technically, the repetition and the magnetic field values in a repet…

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…

Possible evidence for Harper broadening in the yellow exciton series of Cu2O at ultrahigh magnetic fields

Zhuo Yang, Jinbo Wang, Yuto Ishii +3

Hydrogen-like systems in ultra-high magnetic fields are of significant interest in interdisciplinary research. Previous studies have focused on the exciton wavefunction shrinkage u…

Large magnetostriction and first-order phase transition induced by ultrahigh magnetic fields in VO

Yuto Ishii, Akihiko Ikeda, Yasuhiro. H. Matsuda

VO exhibits the metal-insulator transition (MIT) at around 150 K with the formation of vanadium-vanadium (V-V) dimers. We measured the magnetostriction of VO…

X-ray free-electron laser observation of giant and anisotropic magnetostriction in -O at 110 Tesla

Akihiko Ikeda, Yuya Kubota, Yuto Ishii +18

In strong magnetic fields beyond 100 T, the significant Zeeman energy competes with the lattice interactions, where a considerable magnetostriction is expected. However, the micros…

Phonon hydrodynamic regimes in sapphire

Takuya Kawabata, Kosuke Shimura, Yuto Ishii +7

When an ideal insulator is cooled, four regimes of thermal conductivity are expected to emerge one after another. Two of these, the Ziman and the Poiseuille, are hydrodynamic regim…

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…

Longitudinal Magnetoresistance in YBaCuO at High Magnetic Fields of up to 100 T

Shiyue Peng, Xu-Guang Zhou, Yasuhiro H. Matsuda +7

The investigation of transport characteristics in high-temperature superconductors under magnetic fields is one of the most important topics in condensed matter physics and transpo…

Gradual charge order melting in Bi0.5Ca0.5MnO3 induced by ultrahigh magnetic field

Y. Ishii, A. Ikeda, M. Tokunaga +3

We have investigated the magnetic properties of Bi0.5Ca0.5MnO3 under ultrahigh magnetic fields by magnetization measurements. This compound shows the metamagnetic transition which…
