Popis:	The authors report 1 3 C NMR and magnetization measurements on the magnetic state of oriented single crystals of the organic superconductor κ-(BEDT-TTF) 2 Cu[N(CN) 2 ]Cl. To understand these data a spin Hamiltonian based onthe Pnma symmetry of the crystal is developed. When interpreted in the context of this Hamiltonian, the measurements provide a detailed picture of the spin ordering. It is found that the Dzialoshinskii-Moriya (DM) interaction is largely responsible for the details of the ordering above the spin-flop field. Of particular note, the interplane correlations are determined by the intraplane DM interactions and the direction of the applied field.
