RESISTIVITY OF TERNARY CHEVREL-PHASE SUPERCONDUCTORS

摘要

We have measured the resistivities of a series of superconducting Chevrel-phase compounds from 4.2 K to 400 K. All show strong negative curvature d2ρ/dT2 above about 60 K, similar to that observed i n the A-15 compounds. Room temperature resistivities are high, in the 10-3 Ω cm range.
