Abstract
We report on the study of the modification of the electron-quasiparticle in teraction (EQI) function in Stoner enhanced paramagnet CeNi5 when magnetic Nd-ions are substituting Ce-ions, using point-contact (PC) spectroscopy. Th e intensity of the spin fluctuations peak at similar to 2.5 meV in CeNi5 de creases with increasing Nd content and it vanishes for x = 0.5. The CEF pea k from Nd-ions arises at x = 0.5, in the magnetically ordered state. (C) 20 00 Elsevier Science B.V. All rights reserved.
