abstract = {The crystalline structure of spinels is extremely flexible due to the presence of several sublattices in which the cations can be distributed and localized in different crystallographic sites depending on their sizes, oxidation states or coordination numbers. Cationic substitution and ions- extraction are appropriate tools to change the oxidation state inside the spinel structure, thus substantially modifying the magnetic properties. The spinel sulfide CuCr2S4 is a metallic ferromagnet with T-C=377 K, where Cr is mixed- valence Cr3+/Cr4+, while CuTi2S4 is a Pauli paramagnet, with Ti in a mixed- valence state (singlet ground state for Ti3+; nonmagnetic},
