Fig. 7: High-energy magnetic excitations in K2Co(SeO3)2 in the supersolid phase.
From: Wannier states and spin supersolid physics in the triangular antiferromagnet K2Co(SeO3)2
False-color plot of neutron scattering intensity measured on K2Co(SeO3)2 at the AMATERAS spectrometer with Ei = 7.73 meV at T = 70 mK and H = 0, as a function of energy and wave vector transfers along high-symmetry directions in the Brillouin zone. The energy resolution is 0.24 meV at the elastic position. The data were integrated over ±0.5 r.l.u. in l and ± 0.05 r.l.u. in the (h, k, 0) plane perpendicular to the cut, and averaged over equivalent paths shown in Supplementary Fig. 5. No background has been subtracted. White hexagon represents the Brillouin zone boundary. Γ, K and M label high symmetry points in the reciprocal space. Labels above the top axis indicate the positions of energy-cuts shown in Fig. 9.
