Odd-Parity Crystalline Electric Field and Multipoles in Icosahedral Quasicrystal and Approximant: Magnetic Toroidal and Electric Dipoles in Ce-Based Systems
Shinji Watanabe, Syunta Furuya, Mitsuaki Kawamura
Quasicrystals (QCs) lack periodic arrangement of atoms but possess unique structural order distinct from periodic crystals and random systems. The electronic property is far from c…
Ground-State Phase Diagram of the Effective Model with Antiferromagnetic Nearest-Neighbor and Ferromagnetic Next-Nearest-Neighbor Interactions in 1/1 Periodic Approximants to Icosahedral Quasicrystals
Shinji Watanabe
By performing complete enumeration of all configurations of magnetic moments, we have determined the ground-state phase diagram of the effective model with antiferromagnetic neares…
Non-Collinear and Non-Coplanar Magnetic Orders in 1/1 Periodic Approximant to the Icosahedral Quasicrystal
Shinji Watanabe, Tatsuya Iwasaki
Ground-state properties of rare-earth based 1/1 periodic approximants of icosahedral quasicrystal are clarified theoretically on the basis of an effective model for magnetism takin…
Effect of magnetic field on whirling-anti-whirling order in icosahedral-quasicrystal approximant
Shinji Watanabe, Tatsuya Iwasaki
Recent neutron measurement in the icosahedral quasicrystal approximant Au-SM-Tb (SM=Al, Ga) has revealed unique noncollinear magnetic order ``whirling-anti-whirling states''. Here,…
Monte Carlo study on critical exponents of the classical Heisenberg model in ferromagnetic icosahedral quasicrystal
Shinji Watanabe, Tsunetomo Yamada, Hiroyuki Takakura +1
Quasicrystals (QCs) lack three-dimensional periodicity of atomic arrangement but possess long-range structural order, which are distinct from periodic crystals and random systems.…
Predicted versatile topological nodal magnons in Tb-based icosahedral quasicrystal 1/1 approximants
Rintaro Eto, Masahito Mochizuki, Shinji Watanabe
Using a recently-established band representation analysis, we discover two distinct types of topological nodal magnons in the real-space antiferroic ordering of whirling spin arran…
Dynamical and Static Structure Factors in Hedgehog-Antihedgehog Order in Icosahedral 1/1 Approximant Crystal
Shinji Watanabe
Recent discoveries of magnetic long-range orders in the icosahedral quasicrystal and topological magnetic structures on the icosahedron (IC) as the hedgehog state and the antihedge…
Pressure-Induced Valence Crossover and Novel Metamagnetic Behavior near the Antiferromagnetic Quantum Phase Transition of YbNiGa
K. Matsubayashi, T. Hirayama, T. Yamashita +7
We report electrical resistivity, ac magnetic susceptibility and X-ray absorption spectroscopy measurements of intermediate valence YbNiGa under pressure and magnetic f…
