Abstract We have used the recently established linear correlation between the total intensities of the {ital L}{sub 3,2} ``white lines`` in electron energy-loss spectroscopy and the number of unoccupied 3{ital d} states to probe the local electronic structure in epitaxially grown Co--Cr thin films. The significant enhancement of saturation magnetization measured for these epitaxial films, when compared to homogenized bulk alloys, has been correlated directly to the unoccupied 3{ital d} states to the Co atoms in these materials. These measurements are the first direct electronic structure evidence that may support models associating the enhancement of saturation magnetization with {ital intragranular} segregation in Co--Cr thin films. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
