Signature of spin-triplet exciton condensations in LaCoO at ultrahigh magnetic fields up to 600 T
Akihiko Ikeda, Yasuhiro H. Matsuda, Keisuke Sato +5
Bose-Einstein condensation of electron-hole pairs, exciton condensation, has been effortfully investigated since predicted 60 years ago. Irrefutable evidence has still been lacking…
Two Spin-State Crystallizations in LaCoO
Akihiko Ikeda, Yasuhiro H. Matsuda, Keisuke Sato
We report a magnetostriction study of a perovskite above 100 T using our state-of-the-art strain gauge to investigate an interplay between electron correlations an…

High-speed 100 MHz strain monitor using fiber Bragg grating (FBG) and an optical filter has been devised for the magnetostriction measurements under ultrahigh magnetic fields. The…
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^{-…
Spin state ordering of strongly correlating LaCoO induced at ultrahigh magnetic fields
Akihiko Ikeda, Toshihiro Nomura, Yasuhiro H. Matsuda +3
Magnetization measurements of LaCoO have been carried out up to 133 T generated with a destructive pulse magnet at a wide temperature range from 2 to 120 K. A novel magnetic…
Existence of a phase transition under finite magnetic field in the long-range RKKY Ising spin glass DyYRuSi
Y. Tabata, K. Matsuda, S. Kanada +5
A phase transition of a model compound of the long-range Ising spin glass (SG) DyYRuSi, where spins interact via the RKKY interaction, has been investigat…
Interplay between quantum criticality and geometrical frustration in Fe3Mo3N with stella quadrangula lattice
Takeshi Waki, Shinsuke Terazawa, Teruo Yamazaki +7
In the eta-carbide-type correlated-electron metal Fe3Mo3N, ferromagnetism is abruptly induced from a nonmagnetic non-Fermi-liquid ground state either when a magnetic field (~14 T)…
Mean-field type Ising spin glass in a diluted rare-earth intermetallic compound
Y Tabata, K Matsuda, S Kanada +4
We have investigated a phase transition of a long-range RKKY Ising spin glass \dyyrusi by means of the dc and the ac magnetization measurements. The static nonlinear susceptibility…
