Аннотация:Specific heat C(T) and magnetic susceptibility chi(T) of CdV2O4, ZnV2O4 and MgTi2O4 pellet samples have been studied over a wide temperature range. At lower temperature, both V-based spinels exhibit structural transitions followed by antiferromagnetic ordering, T-S = 89 K, T-N = 30 K in CdV2O4, and T-S = 45 and T-N = 31 K in ZnV2O4. In Ti-based spinel the complex metal-insulator-phase transformation occurs at T-MI = 260 K comprising of structural transition and a spin-singlet ground state formation. (C) 2005 Elsevier B. V.
