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…
Observations of Quantum Hall Effect and Inter-Band Effects of Magnetic fields on Hall Conductivity in Organic Massless Dirac Fermion System -(BETS)I under Pressure
K. Iwata, A. Koshiba, Y. Kawasugi +2
We investigated the magnetoresistance and the Hall effect in an organic massless Dirac fermion system -(BETS)I under pressure. The Fermi energy of this system is slightl…
Evidence for three-dimensional Dirac semimetal state in strongly correlated organic quasi-two-dimensional material
Naoya Tajima, Yoshitaka Kawasugi, Takao Morinari +3
The three-dimensional Dirac semimetal is distinct from its two-dimensional counterpart due to its dimensionality and symmetry. Here, we observe that molecule-based quasi-two-dimens…
Coherent interlayer coupling in quasi-two-dimensional Dirac fermions in -(BEDT-TTF)I
Naoya Tajima, Yoshitaka Kawasugi, Takao Morinari +3
Theoretical and experimental studies have supported that the electronic structure of -(BEDT-TTF)I under pressure is described by two-dimensional Dirac fermions. When the…
Fragmented Electronic Spins with Quantum Fluctuations in Organic Mott Insulators near Quantum Spin Liquid
Shigeki Fujiyama, Reizo Kato
Magnetic structures of organic Mott insulators X[Pd(dmit)2]2 (X=Me4P, Me4Sb), of which electronic states are located near quantum spin liquid (X=EtMe3Sb), are demonstrated by 13C N…
