摘要：
The resistivity rho(T) of the incommensurate antiferromagnet CeCu5.8 Au-0.2 as measured along the a direction shows an increase below the ordering temperature T-N = 0.25 K. T-N decreases under hydrostatic pressure, reaching zero around p(c) similar to 5 kbar. Beyond p(c) Fermi-liquid behavior rho = rho(o) AT(2) is recovered over a T range increasing with rho. The residual resistivity po is found to decrease strongly from 93 to 66 mu Omega cm between 0 and 9.8 kbar. (C) 2000 Elsevier Science B.V. All rights reserved.
