Tetrahedrally ferromagnetic correlations and a glassy-freezing anomaly in the breathing pyrochlore magnet with partial -site disorder
Yuya Haraguchi, Masahiro Kitamura, Masaki Gen +6
We investigate the chromium breathing pyrochlore sulfide , a chromium-based thiospinel, by synchrotron x-ray and neutron powder diffraction, dc magnetization,…
Non-linear transport in field-induced insulating states of graphite
Masashi Tokunaga, Kazuto Akiba, Hiroshi Yaguchi +2
Graphite exhibits multi-stage phase transitions in the quantum-limit states realized by magnetic fields applied along the c-axis. Despite extensive studies on this phenomenon, the…
Experimental benchmark of the quantum-classical crossover in a spin ladder
Hironori Yamaguchi, Itsuki Shimamura, Akira Matsuo +4
We report a spin-(1/2, 5/2) three-leg ladder realized in a radical-Mn polymer, exhibiting an antiferromagnetic transition and magnetization curves accurately described by classical…
Quantum phase with spontaneous translational symmetry breaking in an extended diamond chain
Hironori Yamaguchi, Shunsuke C. Furuya, Yu Tominaga +2
We report the experimental realization of a spin-1/2 extended diamond chain in a verdazyl-Cu complex, where competing interactions and lattice distortions give rise to exotic quant…
Frustrated Diamond Lattice Antiferromagnet CoTiO with a Vacancy-ordered Spinel Structure Synthesized via a Topochemical Reaction
Rio Kumeda, Yuya Haraguchi, Daisuke Nishio-Hamane +3
Metastable CoTiO was synthesized through a topochemical reaction using LiCoTiO as the precursor, resulting in a vacancy-ordered spinel structure. Crystal st…
One-third magnetization plateau in a spin-1 kagome magnet BaNi(AsO)(OH)
Yuya Haraguchi, Jun-ichi Yamaura, Akira Matsuo +2
We investigate the structural and magnetic properties of BaNi(AsO)(OH), focusing on its spin-1 kagome lattice and the intricate coexistence of ferromagnetic and ant…
CaCoTeO: A topochemically prepared 3 honeycomb Kitaev magnet
Yuya Haraguchi, Yuto Yoshida, Akira Matsuo +2
We report the magnetic properties of CaCoTeO as a Kitaev candidate. CaCoTeO was synthesized through a topochemical process, wherein all Na ions in NaCoT…
Properties of an organic model Haldane chain system
Ivan Jakovac, Tonči Cvitanić, Denis Arčon +14
We present the properties of a new organic antiferromagnetic chain system -NOPhBNO (abbreviated BoNO). In this biradical system two unpaired electrons from aminoxyl gr…
Quantum spin state stabilized by coupling with classical spins
Hironori Yamaguchi, Tsuyoshi Okubo, Akira Matsuo +5
We introduce a model compound featuring a spin-1/2 frustrated square lattice partially coupled by spin-5/2. A significant magnetization plateau exceeding 60 T could be observed, in…
Kitaev Spin Liquid Candidate OsxCl3 Comprised of Honeycomb Nano-Domains
K. Kataoka, D. Hirai, T. Yajima +11
An osmium chloride with the chemical formula of OsxCl3 (x = 0.81) was synthesized and its crystal structure and thermodynamic properties were investigated. OsxCl3 crystallizes in a…
Various regimes of quantum behavior in S = 1/2 Heisenberg antiferromagnetic chain with fourfold periodicity
