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,…
Pressure-Tuned Metamagnetism and Emergent Three-Body Interactions in CsFeCl
K. Nihongi, T. Kida, Y. Narumi +11
We present a combined experimental and theoretical study of the triangular-lattice quantum antiferromagnet CsFeCl under high magnetic fields and high pressure. Pulsed-field mag…
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…
