摘要：

The intermetallic compound CeNi5, where Ce is not magnetic and in the maximum valence state, is an enhanced Pauli paramagnet in which spin fluctuations are present. For point contacts between a CeNi5 single crystal and Cu, the second derivatives of the I-V characteristics reveal a maximum at low voltages (around 3 mV) which disappears in applied magnetic fields above 10 T. This behaviour in the point-contact spectra is ascribed to the quenching of spin fluctuations by the magnetic field.
