Dynamical lattice instability versus spin liquid state in a frustrated spin chain system

V. Gnezdilov, P. Lemmens, Yu. G. Pashkevich +4

The low-dimensional s=1/2 compound (NO)[Cu(NO3)3] has recently been suggested to follow the Nersesyan-Tsvelik model of coupled spin chains. Such a system shows unbound spinon excit…
