摘要：

We discuss, with reference to our de Haas van Alphen (dHvA) measurements and supporting band calculations, the two low temperature states of the heavy fermion paramagnet CeRu2Si2 which are separated by a steep metamagnetic cross-over. While we are able to propose a consistent Fermi surface model for the paramagnetic state, the high field state continues to evade comprehensive understanding.
