Observation of thermodynamics originating from a mixed-spin ferromagnetic chain
H. Yamaguchi, S. C. Furuya, S. Morota +6
We present a model compound that forms a mixed-spin ferromagnetic chain. Our material design, based on the organic radicals, affords a verdazyl-based complex (p-Py-V)2[Mn(hfac)2].…
Quantized edge magnetizations and their symmetry protection in one-dimensional quantum spin systems
Shunsuke C. Furuya, Masahiro Sato
The bulk electric polarization works as a nonlocal order parameter that characterizes topological quantum matters. Motivated by a recent paper [H. Watanabe \textit{et al.}, Phys. R…
Control of superexchange interactions with DC electric fields
Shunsuke C. Furuya, Kazuaki Takasan, Masahiro Sato
We discuss DC electric-field controls of superexchange interactions. We first present generic results about antiferromagnetic and ferromagnetic superexchange interactions valid in…
Anomalies of kagome antiferromagnets on magnetization plateaus
Shunsuke C. Furuya, Yusuke Horinouchi, Tsutomu Momoi
We discuss the ground-state degeneracy of spin- kagome-lattice quantum antiferromagnets on magnetization plateaus by employing two complementary methods: the adiabatic flux in…
Anisotropy-induced soliton excitation in magnetized strong-rung spin ladders
Yu. V. Krasnikova, S. C. Furuya, V. N. Glazkov +3
We report low temperature electron spin resonance experimental and theoretical studies of an archetype strong-rung spin ladder material (CHN)CuBr.…
Field-induced dimer orders in quantum spin chains
Shunsuke C. Furuya
Field-induced excitation gaps in quantum spin chains are an interesting phenomenon related to confinements of topological excitations. In this paper, I present a novel type of this…
