Fluctuation induced phase of CsCuCl3 in the c-plane field: high field results

Continuing our neutron diffraction experiments in the external fields up to 14.5 T on the frustrated antiferromagnet CsCuCl3, we found two new features: (1) broad central peaks appear in addition to the peaks characterising the two incommensurate phases investigated so far; (2) the spiral vector which has a complicated temperature dependence at low and medium fields becomes temperature independent in high field.
