DOIAbstract
We present a detailed pressure study of the electrical resistivity p(T) and the specific heat C(T) of the non-Fermi- liquid (NFL) compound YbRh2Si2, and of p(T) for a single crystal in which 5 at.% of Si is replaced by isoelectronic Ge. The magnetic phase diagram is deduced up to p congruent to 2.5 GPa. A comparison of the effects of the volume change introduced by doping and/or by hydrostatic pressure will be given. We show that the NFL behaviour observed in p (T) as well as the magnetic phase diagram are not influenced by the disorder introduced by alloying
