Show affiliationsIn the search for new materials exhibiting both ferromagnetic and semiconducting properties, approximately 10% Fe has been incorporated into the large gap semiconductor In2S3, resulting in a new spinel compound Fe0.76In2.17S4. Magnetic measurements show properties of a canonical spin glass state below a freezing temperature of TF = 5 K. Standard powder x-ray diffraction at room temperature revealed the cubic spinel structure. Further structural investigations by high-resolution neutron powder diffraction in the temperature range 1.6 K ≤T≤280 K confirmed the spinel structure with an almost complete cation inversion corresponding to an inversion parameter of 0.94. A mutually consistent description of the neutron diffraction data, EDX analysis and magnetic measurements show that the present compound may be written as 
, with 
denoting vacancies. No magnetic intensities could be observed, in agreement with a spin glass state.
