Abstract

The pyrochlore compounds Bi₂Pt₂O₇ (insulator) and Pb₂Ru₂O_6.5 (metallic conductor) form a continuous series of solid solutions Bi_2-xPb_xPt_2-xRu_xO_7-z. Increasing substitution of the platinum by ruthenium results in a gradual insulator-metal transition. Metallic conductivity is found for a substitution level of x ≳ 1.5. The presence of variable range hopping conductivity in the insulating regime strongly suggests that the metal-insulator transition is of Anderson type.
