✦ Synopsis

Detailed resistivity and susceptibility measurements are reported on Li(Ti~_xVx)204 specimens for 0 < x < 0.05. Even low V-doping strongly suppresses the superconductivity. For x = 0.05, the superconductivity is almost smeared out. The localized magnetic moment per V atom is estimated to be about 1.7/z B which indicates the V 4+ state with S = ½. The localized magnetic moments induced by the V-doping are responsible for the pair breaking and the extreme sensitivity of the superconductivity.
