 abstract = {A recent, major, puzzle in the core-level photoemission spectra of doped
manganites is the observation of a 1 - 2 eV wide shoulder with intensity
varying with temperature T as the square of the magnetization over a T
scale of order 200 K, an order of magnitude less than electronic
energies. This is addressed and resolved here, by extending a recently
proposed two-fluid polaron - mobile electron model for these systems to
include core-hole effects. The position of the shoulder is found to be
determined by Coulomb and Jahn-Teller energies, while its spectral
weight is determined by the mobile electron energetics which is strongly
T and doping dependent, due to annealed disorder scattering from the
polarons and the t(2g) core spins. Our theory accounts quantitatively
for the observed T dependence of the difference spectra, and
furthermore, explains the observed correspondence between spectral
changes due to increasing doping and decreasing T. Copyright (c) EPLA,
