Experimental Verification of Charge Soliton Excitations in the Ionic Mott-Peierls Ferroelectric, TTF-CA
R. Takehara, H. Adachi, K. Sunami +5
Strong coupling of charge, spin, and lattice in solids brings about emergent elementary excitations with their intertwining and, in one dimension, solitons are known as such. The c…
Pressure control of the magnetic anisotropy of the quasi-two-dimensional van der Waals ferromagnet CrGeTe
T. Sakurai, B. Rubrecht, L. T. Corredor +10
We report the results of the pressure-dependent measurements of the static magnetization and of the ferromagnetic resonance (FMR) of CrGeTe to address the properties of…
Separation of Charge Instability and Lattice Symmetry Breaking in an Organic Ferroelectric
Ryosuke Takehara, Keishi Sunam, Fumitatsu Iwase +5
We investigate the charge and lattice states in a quasi-one-dimensional organic ferroelectric material, TTF-QCl, under pressures of up to 35 kbar by nuclear quadrupole resona…
Insulating nature of strongly correlated massless Dirac fermions in an organic crystal
Dong Liu, Kyohei Ishikawa, Ryosuke Takehara +3
Through resistivity measurements of an organic crystal hosting massless Dirac fermions with a charge-ordering instability, we reveal the effect of interactions among Dirac fermions…
