Phonon spectrum in the spin-Peierls phase of CuGeO
L. Spitz, A. Razpopov, S. Biswas +10
CuGeO has long been studied as a prototypical example of the spin-Peierls transition in a Heisenberg chain. Despite intensive investigation of this quasi-one-dimensio…

Spin dynamics of triple-Q magnetic orderings in a triangular lattice: Implications for multi-Q orderings in general two-dimensional lattices
Pyeongjae Park, Woonghee Cho, Chaebin Kim +7
Multi-Q magnetic structures on two-dimensional (2D) lattices provide a key route to realizing topological physics in 2D magnetism. A major experimental challenge is to unambiguousl…

Reexamination of the charge-ordered dimer pattern in the spinel compound CuIr2S4 using single-crystal synchrotron x-ray diffraction
T. Ohashi, N. Katayama, K. Kojima +11
We have re-investigated the crystal structure of a spinel type CuIr2S4 at low temperatures using a single-crystal in a synchrotron radiation x-ray diffraction experiment. The cryst…
