Abstract

The discovery of the new β-pyrochlore oxide superconductor CsOs ₂O₆ with T_c = 3.3 K is reported. It is the third superconductor in the family of β-pyrochlore oxides, following KOs₂O₆ with T_c = 9.6 K and RbOs ₂O₆ with T_c = 6.3 K. The T_c of this series decreases with increasing ionic radius of alkaline metal ions, imposing a negative chemical pressure upon the Os pyrochlore lattice.
