Ferroelectric transition of a chiral molecular crystal BINOL2DMSO
Toshihiro Nomura, Takeshi Yajima, Zhuo Yang +7
We report dielectric, thermodynamical, acoustic, and optical properties of a chiral molecular crystal, 1,1'-bi-2-naphthol 2-dimethylsulfoxide (BINOL2DMSO). We find two successive p…
High-mobility two-dimensional carriers from surface Fermi arcs in magnetic Weyl semimetal films
Shingo Kaneta-Takada, Yuki K. Wakabayashi, Yoshiharu Krockenberger +10
High-mobility two-dimensional carriers originating from surface Fermi arcs in magnetic Weyl semimetals are highly desired for accessing exotic quantum transport phenomena and for t…
Higher magnetic-field generation by a mass-loaded single-turn coil
M. Gen, A. Ikeda, S. Kawachi +4
Single-turn coil (STC) technique is a convenient way to generate ultrahigh magnetic fields of more than 100 T. During the field generation, the STC explosively destructs outward du…
Crystal-Field Paschen-Back Effect on Ruby in Ultrahigh Magnetic Fields
Masaki Gen, Tomoki Kanda, Takashi Shitaokoshi +2
Zeeman spectra of the R lines of ruby (Cr: -AlO) were studied in ultrahigh magnetic fields up to 230 T by magneto-photoluminescence measurements. The observed…

- phase diagram of solid oxygen
Toshihiro Nomura, Yasuhiro H. Matsuda, Tatsuo C. Kobayashi
Comprehensive magnetic-field-temperature (-) phase diagram of solid oxygen including the phase is discussed in the context of the ultrahigh-field measurement and the magn…
High-speed 100 MHz strain monitor using fiber Bragg grating and optical filter for magnetostriction measurements under ultrahigh magnetic fields
Akihiko Ikeda, Toshihiro Nomura, Yasuhiro H. Matsuda +4
A high-speed 100 MHz strain monitor using a fiber Bragg grating, an optical filter, and a mode-locked optical fiber laser has been devised, which has a resolution of $ΔL/L\sim10^{-…
- and - phase boundaries of solid oxygen observed by adiabatic magnetocaloric effect
Toshihiro Nomura, Yoshimitsu Kohama, Yasuhiro H. Matsuda +2
The magnetic-field-temperature phase diagram of solid oxygen is investigated by the adiabatic magnetocaloric effect (MCE) measurement with pulsed magnetic fields. Relatively large…
Irreversible Heating Measurement with Microsecond Pulse Magnet: Example of the alpha-theta Phase Transition of Solid Oxygen
Toshihiro Nomura, Yasuhiro H. Matsuda, Shojiro Takeyama +1
Dissipation inevitably occurs in first order phase transitions, leading to the irreversible heating. Conversely, the irreversible heating effect could be a clue for the first order…
