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…
Thermal Hall Effects of Spins and Phonons in Kagome Antiferromagnet Cd-Kapellasite
Masatoshi Akazawa, Masaaki Shimozawa, Shunichiro Kittaka +7
We have investigated the thermal-transport properties of the kagome antiferromagnet Cd-kapellasite (Cd-K). We find that a field suppression effect on the longitudinal thermal condu…
A series of magnon crystals appearing under ultrahigh magnetic fields in a kagomé antiferromagnet
R. Okuma, D. Nakamura, T. Okubo +7
Search for a new quantum state of matter emerging in a crystal is one of recent trends in condensed matter physics. For magnetic materials, geometrical frustration and high magneti…
