The image states on epitaxial films of iron and cobalt on Cu(100) have been investigated. For iron the energies can be related to the variation of the film morphology with coverage due to the extreme surface sensitivity of the image states. With the help of spin-selective excitations of electrons into the image states, the exchange splitting of the first image state on 7 ML of Fe on Cu(100) could be determined to 65 +/- 15 meV. The exchange splitting for a 6-ML Co film is 55 +/- 10 meV. These results are in agreement with a ferromagnetic order of the surfaces and can be obtained without magnetization of the sample.
