Conference paper


The spinel MgTi2-xVxO4 system was prepared under an argon atmosphere and the structural and electrical properties of these polycrystalline samples were investigated. XRD analysis showed the presence of the spinel phase as the major product and traces of (Ti,V)2O3 as impurities. Solid-solution formation was confirmed from the continuous decrease of the unit cell parameter. The temperature dependence of resistivity for x≥0.2 was explained as a mixture of variable range hopping at low temperatures and thermally activated hopping at high temperatures. A minimum of activation energy was observed at x=1.0.
