Search for quantum-tricritical-point in antiferromagnet CeRu(SiGe)
H. Shinya, F. Ito, N. Kabeya +2
CeRuSi is a well-known heavy fermion paramagnet, and substituting Ge for Si induces antiferromagnetism. This antiferromagnetism is Ising-like and has a tricritical point in…
Material realization of spinless, covalent-type Dirac semimetals in three dimensions
Yuki Tanaka, Rinsuke Yamada, Manabu Sato +2
Realization of a three-dimensional (3D) analogue of graphene has been a central challenge in topological materials science. Graphene is stabilized by covalent bonding unlike conven…
Universal Role of Combined Symmetry for the Protection of the Dirac Cone in Antiferromagnetic Topological Insulators
Asuka Honma, Noriyuki Kabeya, Seigo Souma +13
Antiferromagnetic topological insulators (AF TIs) are predicted to exhibit exotic physical properties such as gigantic optical and topological magnetoelectric responses. While a ke…
Variation of Pressure-Induced Valence Transition with Approximation Degree in Yb-Based Quasicrystalline Approximants
Keiichiro Imura, Yuki Yoneyama, Hideyuki Ando +6
We have synthesized new Tsai-type Yb-based intermediate-valence approximant crystals (ACs) with different degree of approximation to quasicrystal, Zn--Au--Yb 1/1 and 2/1 AC, and st…
Helical Ordering of Spin Trimers in a Distorted Kagome Lattice of GdRuAl Studied by Resonant X-ray Diffraction
Takeshi Matsumura, Yusaku Ozono, Shintaro Nakamura +2
Successive magnetic phase transitions at =17.5 K and =18.5 K in GdRuAl, with a distorted kagome lattice of Gd ions, is studied using resonant X-ray diffrac…
Magnetic Phases of Frustrated Ferromagnetic Spin-Trimer System Gd_3_Ru_4_Al_12_ With a Distorted Kagome Lattice Structure
S. Nakamura, N. Kabeya, M. Kobayashi +3
The magnetization and specific heat measurements have been performed on single-crystalline Gd_3_Ru_4_Al_12_ with a distorted Kagome lattice structure. This spin system is regarded…
Pressure-Temperature Phase Diagram of Golden SmS
Keiichiro Imura, Kazuyuki Matsubayashi, Hiroyuki S. Suzuki +3
We measured the thermal expansion of the valence fluctuating phase of SmS (golden SmS) to construct a pressure vs temperature phase diagram. The obtained phase diagram is character…
