Spin density wave in (FexV3−x)S4 and the coexistence of normal and condensate states: A Mössbauer study

► FexV3−xS4(1.0≤x≤2.0) system was investigated by 57Fe Mössbauer Spectroscopy. ► Incommensurate spin density wave (SDW) has been found in this system. ► We report the temperature evolution of the condensate density of SDW state. ► For composition (x=1.0) the SDW is unpinned while for (x>1.0) is pinned.
