Popis: The structural, magnetic and transport properties have been studied of Li doped CoV2O4 and FeV2O4. Li doping increases the ferri-magnetic ordering temperature of both the samples but decreases the spin-glass transition temperature of CoV2O4. The Li-doping decreases the V-V distance which in effect increases the A-V coupling. Thus the increased A-V coupling dominate over the decrease in A-V coupling due to doping of non-magnetic Li.
