Abstract
Ce(Ru0.85Rh0.15)(2)Si-2 is the itinerant antiferromagnetic heavy-fermion co mpound (Neel temperature T-N = 5.5 K). The temperature dependence of electr ical resistivity parallel and perpendicular to the tetragonal c-axis on a s ingle-crystalline sample of this compound has been measured under hydrostat ic pressure up to 2 GPa. It is found that T-N is depressed with pressure at the rate of (dT(N)/dP)(p-->0) = - 3.9 K/GPa. Such a strong dependence on p ressure is seen as a consequence of the delicate Fermi-surface nesting that results in a spin-density-wave transition. (C) 1999 Elsevier Science B.V. All rights reserved.
