Zusammenfassung:
We have investigated the properties of Yb(2)Ni(2)Al by means of
resistivity, susceptibility and specific heat measurements. Our results
suggest that it is the first magnetically non-ordered Yb heavy-fermion
system with a low characteristic energy and clear coherence effects in
the resistivity. A logarithmic temperature dependence of CIT indicates
that it is close to the transition to a magnetic ordered ground state.
We further found a simple systematic for composition dependence of the
Yb-valence in binary and ternary Yb-T-Al compounds (T:Ni, Pd, Pt).
