Title:
Uniaxial Stress Experiments at the Quantum Phase Transition of {{CeCu6}}-{{xAux}}
Abstract:
The resistivity $̊ho$(T) of the heavy-fermion system CeCu6-xAux shows that for x=0.2 the Néel temperature TN rises under uniaxial stress $\sigma$a parallel to the a-axis, in qualitative agreement with previous studies of the specific heat. For x=0.1, near the magnetic quantum phase transition, no hints of magnetic order are observed up to the highest $\sigma$a of 4.5kbar. A detailed discussion of the dependence of $̊ho$0 on hydrostatic and uniaxial pressure is given.
