Abstract
Comprehensive temperature scans of the resistivity of a high-quality sample of were made under different pressures up to 30 kbar; they have revealed that the insulator phase is suppressed completely at , transforming to a non-Fermi-liquid phase in which the resistivity varies as with and 1.60 over a broad pressure range.
