Highly fluctuating double- magnetic order in the van der Waals metal CeTe
Ryutaro Okuma, Yuita Fujisawa, Natsumi Maekawa +5
CeTe is a van der Waals antiferromagnet composed of magnetic [CeTe] layers coupled to highly conducting Te square nets. Its simple quasi-two-dimensional electronic…
Topological Semimetal KAlGe with Novel Electronic Instability
Toshiya Ikenobe, Takahiro Yamada, Jun-ichi Yamaura +6
Compounds with the anti-PbFCl structure exhibit a variety of electronic instabilities and intriguing physical properties. NaAlSi and NaAlGe are similar topological nodal-line semim…
Dimensional reduction by geometrical frustration in a cubic antiferromagnet composed of tetrahedral clusters
Ryutaro Okuma, Maiko Kofu, Shinichiro Asai +10
Dimensionality is a critical factor in determining the properties of solids and is an apparent built-in character of the crystal structure. However, it can be an emergent and tunab…
Universal scaling of the specific heat in quantum kagome antiferromagnet herbertsmithite
H. Murayama, T. Tominaga, T. Asaba +9
Despite tremendous investigations, a quantum spin liquid state realized in spin-1/2 kagome Heisenberg antiferromagnet remains largely elusive. In herbertsmithite ZnCu(OH)Cl…
Magnetization Plateau Observed by Ultra-High Field Faraday Rotation in a Kagomé Antiferromagnet Herbertsmithite
Ryutaro Okuma, Daisuke Nakamura, Shojiro Takeyama
To capture the high-field magnetization process of herbertsmithite (ZnCu3(OH)6Cl2), Faraday rotation (FR) measurements were carried out on a single crystal in magnetic fields of up…
Fermionic Order by Disorder in a van der Waals Antiferromagnet
R. Okuma, D. Ueta, S. Kuniyoshi +11
CeTe3 is a unique platform to investigate the itinerant magnetism in a van der Waals (vdW) coupled metal. Despite chemical pressure being a promising route to boost quantum fluctua…
