Magnetic field dependence of spin dynamics in the frustrated spin-chain system rouaite, Cu?(NO?)(OD)?

Abstract: Cu2(NO3)(OH)3 (mineral name: rouaite) is a spin-1/2 low-dimensional frustrated quantum spin system structurally similar to botallackite, in which interacting magnon and spinon excitations were reported earlier. We have a large deuterated, nearly detwinned mosaic sample of rouaite that was already measured at LET in zero magnetic field recently. In the present proposal we suggest to extend these measurements in a magnetic field, in particular to see the closing of the spin gap at the quantum critical point (~2 T) corresponding to the transition to the so-called "LT-stripe" field-induced phase and to study spin waves in this phase. The field and energy ranges accessible at LET and the high energy resolution are perfectly suited for this measurement.
