We study the changes in the occupied density of states of (Formula presented) as a function of temperature (25-300 K) using photoemission spectroscopy. The spectral weight transfer across the metal-insulator/charge-ordering/ferromagnetic-antiferromagnetic transition is abrupt and over very large energy scales (up to 1.2 eV from the Fermi level (Formula presented) compared to the transition temperature (Formula presented) (∼12 meV) and the gap value in the insulating phase (∼100 meV). Negligible changes observed at (Formula presented) in the ferromagnetic-metallic phase above (Formula presented) and a weak spectral weight transfer across the ferromagnetic-paramagnetic transition at (Formula presented) are consistent with negligible change in carrier density above (Formula presented).
