Enhanced lattice fluctuations prior to a nonmagnetic ferroelectric order in an ionic spin-chain system
Keishi Sunami, Tomohiro Baba, Kazuya Miyagawa +2
We investigated microscopic lattice states in the donor-acceptor ionic Mott insulator, TTF-BA, by Br-NQR spectroscopy to explore cross-correlated fluctuations between spin,…

Magnetic excitations in an ionic spin-chain system with a non-magnetic ferroelectric instability
K. Sunami, Y. Sakai, R. Takehara +4
Cross-correlation between magnetism and dielectric is expected to offer novel emergent phenomena. Here, magnetic excitations in the organic donor-acceptor spin-chain system, TTF-BA…

Fate of a soliton matter upon symmetry-breaking ferroelectric order
K. Sunami, R. Takehara, A. Katougi +6
In a one-dimensional (1D) system with degenerate ground states, their domain boundaries, dubbed solitons, emerge as topological excitations often carrying unconventional charges an…
