  We studied the electronic structure of high quality Cr(110) films grown on
W(110) surface employing photoemission spectroscopy. Experiments on the
differently aged samples revealed distinct signatures of the surface and bulk
features in the electronic structure. It is observed that the adsorbed oxygens
form covalent bonds with the surface Cr atoms at higher temperatures, while
they remain almost unreacted at low temperatures. In addition to the spin
density wave transition induced band folding across the bulk Neel temperature,
we discover a weakly dispersing sharp feature emerging near the Fermi level at
low temperatures presumably due to correlation induced effects.
