Spin Fluctuations from Hertz to Terahertz on a Triangular Lattice

Yusuke Nambu, Jason S. Gardner, Douglas E. MacLaughlin +6

The temporal magnetic correlations of the triangular lattice antiferromagnet NiGa${}_2$S${}_4$ are examined through thirteen decades ($10^{-13}-1$~sec) using ultra-high-resolution inel…
