Spin polarized photoemission is used to examine the development of the magnetic structure in Cr films deposited on an Fe(001) substrate at 50 {degree}C. The spin polarization of the Cr core levels provides a clear indication that within the initial monolayer the moments are antiferromagnetically aligned to those of the substrate. Through comparison with model tight-binding calculations it is shown that at the monolayer limit the Cr moments are of the order of 1.8{mu}{sub {ital B}} or larger. Subsequent Cr monolayers align antiferromagnetically with respect to the previous layer. The tight-binding calculations further indicate that as the Cr film thickness evolves the moment at the solid-vacuum interface is always enhanced.
