Query: Dynamical Mean Field Theory of Double Perovskite Ferrimagnets   The dynamical mean field method is used to analyze the magnetic transition
temperature and optical conductivity of a model for the ferrimagnetic double
perovskites such as $Sr_2FeMoO_6$. The calculated transition temperatures and
optical conductivities are found to depend sensitively on the band structure.
For parameters consistent with local spin density approximation band
calculations, the computed transition temperatures are lower than observed, and
in particular decrease dramatically as band filling is increased, in
contradiction to experiment. Band parameters which would increase the
transition temperature are identified.
