$5/9 -$ Magnetization Plateau and Spin Supersolidity in YCu $_{3}$ (OD) $_{7 - x}$ Br $_{2 + x}$ 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 $_{3}$ (OD) $_{7 - x}$ Br $_{2 + x}$ (YCOB), reveal…

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…

X-ray free-electron laser observation of giant and anisotropic magnetostriction in $I^^{2}$ -O $_{2}$ 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…
