Abstract: The spatial dependence of the magnetic moment perturbation near the (l-l0)-Fe/Co interface was derived from hyperfine fields determined by perturbed angular correlation. The amplitude of the moment perturbation decays exponentially with the distance to the interface. The moment perturbation itself is modulated by a sine function of the distance d to the interface Delta mu = A* exp(-p*\d)*sin(-k*d). Between 90 K and 570 K, we observe that the amplitude and the penetration depth of the perturbation as well as the wave vector of the modulation are essentially constant within the accuracy of the values. In this temperature region the average values for the parameters determining the exact moment perturbation are A = 1.03(mu B), p = 2.25 X 10(9) m and k = 1.45 x 10(10) m(-1) when d is defined positive at the Co side of the interface.
