Abstract

The point-contacts between non-Fermi liquid compound YbCu3.5Al1.5 and Cu in zero magnetic field as well as in applied magnetic fields up to 6 T were studied in the temperature region from 1.5 to 10 K. An asymmetric behaviour of dV/dI(V) is observed with a maximum close to zero voltage. A magnetic field of 6 T splits the maximum into two sub-peaks and diminishes its intensity. The extremum in dV/dI(V) is related to a NFL behaviour and the splitting of this feature by applied magnetic field signifies the destruction of the NFL state.
