dc.description.abstractSpectroscopic, magnetic, thermal, and transport measurements under pressure are presented which were performed on YbCu5−xAlx intermetallics. The substitution of Cu by Al in YbCu5 drives the system from an almost divalent behavior of the Yb ion in YbCu5 to a trivalent state in YbCu3Al2. A compensation between the normal thermal expansion and a valence-driven contraction was found for YbCu4Al. Antiferromagnetic order sets in for x>1.5, where an increasing Al content causes both a growing transition temperature and rising saturation moments reaching 2 K and about 2.1μB, respectively, for x=2. At the critical concentration (x≈1.5) the possibility of a non-Fermi-liquid state is analyzed together with its tuning by pressure.
