Query: Itinerant metamagnetism of CeRu2Si2 : bringing out the dead. Comparison
  with the new Sr3Ru2O7 case   Focus is given on the macroscopic and microscopic experimental works realized
during a decade on the clear case of itinerant metamagnetism in the heavy
fermion paramagnetic compound CeRu2Si2 . Emphasis is made on the feedback
between the band structure, the exchange coupling and the lattice instability.
Sweeps in magnetic field, pressure and temperature feel the pseudogap of this
strongly correlated electronic system as well as its equivalent CeRu2Ge2 at a
fictitious negative pressure. Some mysteries persist as the complete
observation of the FS above the metamagnetic field HM and the detection of the
dynamical ferromagnetic fluctuation near HM. The novelty of the bilayer
ruthenate Sr3Ru2O7 is discussed by comparison. Despite differences in spin and
electronic dimensionality many common trends emerge.
