摘要：

We report temperature-dependent redistribution of spectral weight in photoemission spectra of La0.6Sr0.4MnO3 over a wide energy range of several eV. We attribute this to a change in the electron correlation strength induced by the changing degree of ferromagnetic order with temperature. We discuss the relationship between the temperature-dependent spectral weight close to the Fermi level and the unusual transport properties.
