Neutron scattering experiments have been carried out on a single crystal and powdered specimens of ZnCr2Se4, a helimagnet, above and below the transition at TN=21.2 K. Below TN, crystal belongs to D194h. Atomic parameters of Se can be expressed by a single parameter, «=0.3847. Rather small magnetic moment (1.71 μB at 0 K) and the linear dependence of the length of the screw vector, Q0, on the lattice deformation were observed. Anisotropic critical scattering (Jx/Jy≅3) was measured around (4 — Q0, 0, 0) above TN and Q dependence of the exchange interaction constant, J(Q), near Q0 was discussed. Recent studies by Plumier et al. were critically referred.
