Phys. Rev. Lett. 84, 5168–5171 (2000)Electronic Correlations in ManganitesReceived 23 September 1999; published in the issue dated 29 May 2000 The influence of local electronic correlations on the properties of colossal magnetoresistive manganites is investigated. To this end, a ferromagnetic two-band Kondo lattice model is supplemented with the local Coulomb repulsion missing in this model and is analyzed within dynamical mean-field theory. Results for the spectral function, optical conductivity, and the paramagnetic-to-ferromagnetic phase transition show that electronic correlations have drastic effects and may explain some experimental observations. © 2000 The American Physical Society URL:
