Resistivity and susceptibility near the QCP in disordered UCU5-xNix

摘要

The question of whether the temperature dependences of the magnetic susceptibility and the electrical resistivity of UCu5-xNix near, and away from, the QCP where T-N is suppressed to T = 0 are due to intrinsic fluctuations or are dominated by disorder effects is addressed. The interesting p proportional to log T behavior below 2 K present for 0.75 <= x <= 1. 1 is analyzed and discussed. (c) 2006 Elsevier Inc. All rights reserved.
