摘要
Measurements of the electrical resistivity of U1-xThxBe13 compounds as a function of pressure are presented, which provide a possible explanation for the unusual behavior of these materials. The effect of pressures shown on the resistance R of U0.9828Th0.0172Be13, the composition where the cusp in Tc(x) appears. At ambient pressure, there is no peak in ρ for T≥1.2 K, but for P≥6.2 kbar, Tmax appears at low temperatures and is observed to move to higher temperatures with pressure. Pressure measurements of Tc for x=0.019 and 0.026 reveal a 'kink' in Tc(P) at the temperature-pressure points (0.48 K, 1.3 kbar) and (0.20 K, 5.2 kbar) respectively.
