N2 - The magnetic phase diagram of metallic pyrochlore lattices at the ground state has been studied theoretically in the double-exchange model by using a mean-field approximation. The phase diagram was found to be rather insensitive to the Hund coupling but to show a rich variety in magnetic structure with doping. A crossover between ferromagnetic and spin glass phases observed in (RE)2Mo2O7 is discussed.
