It is shown theoretically that, in contradiction to massive specimens, the work function of ferromagnetic thin films does not depend linearly on the square of magnetization as a consequence of the inhomogeneous magnetization distribution. This theoretical conclusion is confirmed by experimental investigations of gadolinium films as well as interpretation of the results reported for nickel samples.
