Abstract

2 power-law behavior in the low-temperature resistivities. As pressure was increased, T-FL diminished from similar to 11 K at ambient pressure to similar to 0.6 K at 8.23 GPa. Over the same pressure range, the A parameter increased dramatically with a functional form of A proportional to (P -P-c)(-2) with P-c similar or equal to 9.8 GPa being the critical pressure for a possible quantum critical point.
