Abstract
We investigate the periodic Anderson model in the presence of an external m agnetic field, using dynamical mean-field theory in combination with the mo dified perturbation theory. A metamagnetic transition is observed that exhi bits a massive change in the electronic properties. These are discussed in terms of the quasiparticle weight and densities of states. The results are compared with the experimental results of the metamagnetic transition in Ce Ru2Si2.
