To explore novel spin-charge coupled phenomena in the strongly correlated electron system with frustrated lattice, charge transport and dynamics have been investigated for the hole-doped spin-glass (Mott) insulator (Y 1-xCdx)2Mo2O7 with pyrochlore structure. Coincident with the disappearance of spin-glass state by hole doping, a diffusive metallic transport with strongly renormalized electron mass shows up with no long range spin order, which is caused by strong antiferromagnetic spin fluctuation.
