Atomic structure and magnetism of the Au-Ga-Ce 1/1 approximant crystal
Shintaro Suzuki, Azusa Motouri, Kazuhiko Deguchi +6
We report a new Au-Ga-Ce 1/1 approximant crystal (AC) which possesses a significantly wide single-phase region of 53 - 70 at% Au and 13.6 - 15.1 at% Ce. Single crystal X-ray struct…
Enhancement of superconductivity by pressure-induced critical ferromagnetic fluctuations in UCoGe
Masahiro Manago, Shunsaku Kitagawa, Kenji Ishida +3
A Co nuclear quadrupole resonance (NQR) was performed on a single-crystalline ferromagnetic (FM) superconductor UCoGe under pressure. The FM phase vanished at a critical pre…
Interpretation of some Yb-based valence-fluctuating crystals as approximants to a dodecagonal quasicrystal
Tsutomu Ishimasa, Marek Mihalkovič, Kazuhiko Deguchi +2
The hexagonal ZrNiAl-type (space group: P-62m) and the tetragonal Mo2FeB2-type (space group: P4/mbm) structures, which are frequently formed in the same Yb-based alloys and exhibit…
Direct observation of heterogeneous valence state in Yb-based quasicrystalline approximants
M. Matsunami, M. Oura, K. Tamasaku +10
We study the electronic structure of Tsai-type cluster-based quasicrystalline approximants, AuGeYb (AGY-I), AuGeYb (AGY-II), and Zn$_{…
Pressure-Driven Quantum Criticality and T/H Scaling in the Icosahedral Au-Al-Yb Approximant
Shuya Matsukawa, Kazuhiko Deguchi, Keiichiro Imura +2
We report on ac magnetic susceptibility measurements under pressure of the Au-Al-Yb alloy, a crystalline approximant to the icosahedral quasicrystal that shows unconventional quant…
Relationship between Ferromagnetic Criticality and the Enhancement of Superconductivity Induced by Transverse Magnetic Fields in UCoGe
Taisuke Hattori, Kosuke Karube, Kenji Ishida +3
We have performed 59Co NMR experiments on the ferromagnetic superconductor UCoGe under magnetic fields (H) along the a- and b- axes to investigate the relationship between ferromag…
