A heavy-mass electron state is realized in a doped valence bond solid(Ti1-xVx)2O3. In this system, itinerant holes mediate the mainly ferromagneticRKKY interaction between the localized magnetic moments and become readilyspin-polarized under a magnetic field, while showing large negativemagnetoresistance. In spite of the ferromagnetic interaction among thecarriers, their effective mass is found to be 1 or 2 orders of magnitude largerthan that of usual doped semiconductors. Such strong mass renormalization isascribable to the polaron formation on the Ti-dimer, where the spin-singletstate is originally formed. Doping dependence of the electronic specific-heatcoefficient implies that the dimeric lattice fluctuation or softening isresponsible for the enhanced electron-phonon interaction.
