The glassy behavior observed in the pyrochlore magnet Y2Mo2O7, where themagnetic Mo^{4+} ions interact predominantly via isotropic nearest neighborantiferromagnetic exchange, possibly with additional weak disorder, is adistinct class of spin glass systems where frustration is mostly geometrical. Amodel proposed to describe such a spin glass behavior is the Heisenberg modelon a pyrochlore lattice with random but strictly antiferromagnetic exchangedisorder. In this paper, we provide compelling numerical evidence fromextensive Monte Carlo simulations which show that the model exhibits a finitetemperature spin glass transition and thus is a realization of a spin glassinduced by random weak disorder from spin liquid. From our results, we are ledto suggest that the spin glass state of Y2Mo2O7 is driven by effective strongdisorder.
