Revisitng the spin-nematic phase in Linarite

Abstract: Linarite is a natural mineral which displays a rich and complex phase diagram in applied fields up to 10T for temperatures below 2.8K. A frustrated J1-J2 chain system, linarite has recently been proposed to display a spin–nematic phase due to its accessible saturation field of ~9T. This dynamic phase, which can be likened to the spontaneous alignment of rod-shaped molecules in LCD screens, would be observed as a gapped excitation. Recent inelastic neutron scattering measurements in zero field have shown dispersive behaviour both parallel and perpendicular to the Cu-chains which have been successfully modelled with linear spin-wave theory [1]. Our recent LET data (RB1810092), showed a possible gapped state at high fields. Unfortunately due to temperature instability, we were not able to confirm the phase of our sample. We would like to continue this investigation as a function of field.
