Changes to the Higgs mode in the quasi 1-D antiferromagnet SrCo2V2O8
SrCo2V2O8 is an example of a 1-D XXZ Heisenberg antiferromagnet; this maps to the Tomonaga-Luttinger liquid state when paramagnetic. At low temperatures, antiferromagnetic order develops. On applying a field, this can be driven into a longitudinal spin density wave state. At temperatures below 250 mK, on either side of this transition, there is a drop in magnetic Bragg peak intensity that is not due to a spin reorientation or change in domains. We suspec that this is driven by a change in the longitudinal (Higgs) excitation, and request time to measure this excitation in this region.
