One-Parameter Scaling in CeRu 2 Si 2 at High Magnetic Fields: High-Pressure and Magnetostriction Experiments

Résumé

The origin of the metamagnetic-like transition occurring in the heavy-fermion compound CeRu 2 Si 2 has been investigated by means of high-pressure magnetization and resistivity measurements. The zero-field results reveal an extremely strong pressure sensitivity of the Fermi-liquid state, with a huge electronic Grüneisen parameter of about +170. Almost the same value is found for the characteristic field H M of the transition. The magnetostriction is correspondingly large and can be quantitatively accounted for if one assumes the magnetization to obey a simple scaling relation as a function of pressure.
