  We investigate ferromagnetism in the periodic Anderson model with diagonal
disorder. Using dynamical mean-field theory in combination with the modified
perturbation theory, the disorder can be included in the calculation
consistently, which turns out to be equivalent to the CPA method. Disorder
generally reduces the Curie temperature and can for certain configurations
completely suppress ferromagnetic order. This can be ascribed to the enhanced
quasiparticle damping and the special structure of the density of states.
