 Abstract: Ferromagnetic correlations are discussed on the basis of shift K-4f and spin-lattice-relaxation (SLR) rate R-4f (T) = (1/T1T)(4f) investigations for YbNi4P2 and YbRh2Si2. For YbRh2Si2 the coexistence of antiferromagnetic (afm) and ferromagnetic (fm) fluctuations at the edge of magnetic order is strongly related to the non-Fermi-liquid behaviour (NFL). The analysis of the NMR results for YbNi4P2 in the modified Korringa framework for correlated local moment metals yields the enhancement factor kappa(alpha) which is a measure of the q-space dependence of the complex dynamic susceptibility. Surprisingly the kappa(alpha) behavior of YbNi4P2 is very similar to YbRh2Si2 and evidences strongly the evolution of an afm (q not equal 0) component in the q = 0 dominated complex dynamic susceptibility chi ''(q,omega(n),T) at low temperatures and in small fields. This suggests the presence of ferro- and antiferromagnetic fluctuations at the QCP and the freezing out of the afm ones by applying magnetic fields and tuning towards FL state.
