High-field fate of the Kitaev quantum spin liquid in -RuCl
K. Imamura, R. Ohno, Y. C. Tsuzuki +15
Kitaev quantum spin liquids (KQSLs) host fractionalized excitations described by itinerant Majorana quasiparticles and gapped fluxes (visons), providing a platform for emerge…
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…
Magnetoelastic mapping of the high-field phase diagram in the topological cubic helimagnet SrFeO
Masaki Gen, Shun Okumura, Shusaku Imajo +9
The cubic perovskite SrFeO is a prototypical centrosymmetric itinerant magnet that hosts a quadruple- hedgehog-antihedgehog lattice and exhibits a complex magnet…
Magnetization Plateau and Spin Supersolidity in YCu(OD)Br under Magnetic Fields up to 120~T
Hiroaki Hayashi, Han Li, Feng-Feng Song +11
We performed high-precision magnetization measurements up to 120~T on three compositions of the newly discovered kagome antiferromagnet YCu(OD)Br (YCOB), reveal…
Magnetic-field switching of exciton-magnon coupling in LiNiPO
Bei Sun, Zhuo Yang, Julian Shibuya +3
Exciton-magnon transitions provide a fundamental optical fingerprint of coupled excitonic and magnetic excitations in antiferromagnets. However, controlling such coupled excitation…
Unified Description of Spin-Lattice Coupling and Thermodynamics in the Pyrochlore Heisenberg Antiferromagnet
Masaki Gen, Hidemaro Suwa, Shusaku Imajo +6
We study an extended model to describe the spin-lattice coupling, incorporating individual vibrations of bonds and atomic sites alongside distance-dependent exchange interactions.…
