Quantum Phase Transition of Organic Spin Liquid Tuned by Mixing Counterions
K. Ueda, S. Fujiyama, R. Kato
We found a plateau in the magnitude of the isolated magnetic moments as a function of the anisotropy of the transfer integral (t'/t) in the gapless quantum spin liquid (QSL) phase…
Quantum mechanically driven structural-spin glass in two dimensions at finite temperature
Chisa Hotta, Kazumasa Ueda, Masatoshi Imada
In magnetic materials, spins sometimes freeze into spatially disordered glassy states. Glass forming liquids or structural glasses are found very often in three dimensions. However…
Spin waves and spin-state transitions in a ruthenate high-temperature antiferromagnet
H. Suzuki, H. Gretarsson, H. Ishikawa +16
Ruthenium compounds play prominent roles in materials research ranging from oxide electronics to catalysis, and serve as a platform for fundamental concepts such as spin-triplet su…
Theoretical study of a localized quantum spin reversal by the sequential injection of spins in a spin quantum dot
Satoshi Kokado, Kazumasa Ueda, Kikuo Harigaya +1
This is a theoretical study of the reversal of a localized quantum spin induced by sequential injection of spins for a spin quantum dot that has a quantum spin. The system consists…
