Structural and magnetic properties of the spinel CuV2S4 have been studied by means of X‐ray diffraction using synchrotron radiation and measurements of magnetic susceptibility. The structural phase transitions occur at about 55 K and 90 K, and the superlattice reflections (h ± qo, k ± qo, l) having...
