The FeCr2S4 sulfospinel has been synthesized from the elemental components, by high-energy ball milling. The magnetic properties of the resulting crystallites (mean diameter d = 120+/-10 nm) have been studied by means of ac and dc susceptibility, Mossbauer and transport measurements. Magnetization curves showed a para- to ferrimagnetic transition of FeCr2S4 phase at T-C = 165(3) K, and a cusp at T-L approximate to 70 K. The evolution of Mossbauer spectra at different temperatures indicates the existence of a disordered surface layer, and its thickness was estimated to be t = 8(2) nm. Transport measurements show that the onset of the insulator-metal (IM) transition at T =241 K, a similar to30% higher temperature than previous reports. In contrast, the 'colossal' magnetoresistance (CMR) effect observed in bulk FeCr2S4 is greatly reduced.
