Abstract

The field-induced magnetic phase occurring above Hcl ≃ 1.5 T in Cs3Cr2Br9 has been investigated by means of elastic and inelastic neutron scattering. The magnetic structure was determined at H = 6 T and the field dependence of both the Cr3+ average magnetic moment and the propagation vector were measured. The spin dynamics study reveals that the lowest excitation remains gapped above the critical field Hcl.
