Spin dynamics of the $E_{8}$ particles

Xiao Wang, Konrad Puzniak, Karin Schmalzl +7

In this article, we report on inelastic neutron scattering measurements on a quasi-1D antiferromagnet BaCo $_{2}$ V $_{2}$ O $_{8}$ under a transverse magnetic field applied along the (0,1,0)…

Quantum paramagnetic states in the spin-1/2 distorted honeycomb-lattice Heisenberg antiferromagnet -- application to Cu $_{2}$ (pymca) $_{3}$ (ClO $_{4}$ )

Tokuro Shimokawa, Ken'ichi Takano, Zentaro Honda +2

We investigate the ground-state phase diagram of a spin-1/2 honeycomb-lattice antiferromagnetic (AF) Heisenberg model with three exchange interactions, $J_{A}$ , $J_{B}$ , an…

Direct observation of spin-quadrupolar excitations in Sr $_{2}$ CoGe $_{2}$ O $_{7}$ by high field ESR

Mitsuru Akaki, Daichi Yoshizawa, Akira Okutani +4

Exotic spin-multipolar ordering in spin transition metal insulators has so far eluded unambiguous experimental observation. A less studied, but perhaps more feasible fingerprint of…

Long-range magnetic order and interchain interactions in the $S = 2$ chain system MnCl $_{3}$ (bpy)

Randy S. Fishman, Shin-ichi Shinozaki, Akira Okutani +4

A compound with very weakly interacting chains, MnCl $_{3}$ (bpy), has attracted a great deal of attention as a possible $S = 2$ Haldane chain. However, long-range magnetic order of the…
