Weak Ferromagnetism in NiS under Nanocrystallization
Hayato Miyazaki, Tomohiko Yoshinaga, Ojiro Miyazaki +7
Structurally well-ordered NiS nanocrystals with an average diameter of nm retain the bulk-like two-step antiferromagnetic transitions, as shown by magnetization…
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,…
Dominant Kitaev Interaction and Field-induced Quantum Disordered Phase in the Cobaltate NaCoTeO
Xu-Guang Zhou, Han Li, Chaebin Kim +11
The identification of quantum spin liquid phases in Kitaev candidate materials remains a major experimental challenge. Since most Kitaev candidates develop antiferromagnetic (AFM)…
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…
