      abstract     = {The crystal and magnetic structure of multiferroic
                      LiFe(WO4)2 were investigated by temperature and
                      magnetic-field dependent specific heat, susceptibility and
                      neutron diffraction experiments on single crystals.
                      Considering only the two nearest-neighbour magnetic
                      interactions, the system forms a J1, J2 magnetic chain but
                      more extended interactions are sizeable. Two different
                      magnetic phases exhibiting long-range incommensurate order
                      evolve at TN1 $\sim$ 22.2K and TN2 $\sim$19 K. First, a
                      spin-density wave develops with moments lying in the ac
                      plane. In its multiferroic phase below TN2, LiFe(WO4)2
                      exhibits a spiral arrangement with an additional
                      spin-component along b. Therefore, the inverse
                      Dzyaloshinskii-Moriya mechanism fully explains the
                      multiferroic behavior in this material. A partially
                      unbalanced multiferroic domain distribution was observed
                      even in the absence of an applied electric field. For both
                      phases only a slight temperature dependence of the
                      incommensurability was observed and there is no commensurate
                      phase emerging at low temperature or at finite magnetic
                      fields up to 6 T. LiFe(WO4)2 thus exhibits a simple phase
                      diagram with the typical sequence of transitions for a
                      type-II multiferroic material.},
