Abstract
We show that the spectral functions in the ferromagnetic planes of orbitall y ordered LaMnO3 strongly depend on the Jahn-Teller interaction and on the polarization of orbitals around the hole. Using realistic parameters and av ailable experimental information we suggest that the incoherent spectral we ight and the mass enhancement in LaMnO3 might be quite large.
