Abstract

We have studied the magnetic properties and the dHvA effect of CeRu2 ( Si1 - x Gex )2. It is found that the pseudometamagnetic transitions (PMMT) of lower Ge concentration samples are likely to join to the first-order metamagnetic transitions of higher Ge concentration samples, indicating that the PMMT of CeRu2Si2 is a phenomenon closely related with the end point of the first-order metamagnetic transition. The dHvA frequencies change continuously with increasing Ge concentration or increasing unit cell volume across the quantum critical point. It is likely that the electronic states above the pseudometamagnetic and first-order metamagnetic transitions are connected without a phase transition.
