Figure 3. False color image of DCS neutron scattering data [ 3 ] from CuCl sub 2 · 2 ( dimethylsulfoxide ) ( CDC ) in zero field and in a field of 11 Tesla. Spin-1/2 copper atoms shown in red form spin chains with alternating orientation of the coordinating environment, causing an effective staggered field in registry with the lattice in conjunction with the uniform field. The staggered field causes formation of soliton and breathers from spinons as evidenced by resolution limited modes with a finite energy gap.
