Abstract
We have grown by means of Molecular Beam Epitaxy ultrathin (1 to ∼ 10 ML) films of fcc Fe and Co on a Cu(001) surface, thus stabilizing this high temperature phase of bulk Fe and Co at room temperature. All films, including the single monolayers, are ferromagnetic. The Co films are magnetized in plane, independently on the thickness. Fe films thicker than 2 ML are magnetized along the film normal. Up to now, the statistical uncertainty is still too large to conclusively prove an enhancement of the magnetic moment for the thinnest Co films.

Since our discovery of the ferromagnetism of the Fe/Cu(001) system, see D. Pescia, M. Stampanoni, G.L. Bona, A. Vaterlaus, R.F. Willis, F. Meier: Phys. Rev. Lett.58, 2126 (1987), the ferromagnetism of this system has been already confirmed twice, by J. R. Dutcher, B. Heinrich, J.F. Cochran, D.A. Steigerwald, W.F. Egelhoff: J. Appl. Phys. 1988, in press and by R.F. Willis, J.A.C. Bland, W. Schwarzacher: Early attempts to detect ferromagnetism for thin films prepared at room temperature failed probably because of the low Curie temperature of these thin films or because of the perpendicular magnetization [P.A. Montano, G.F. Fernando, B.R. Cooper, E.R. Moog, H.M. Naik, S.D. Bader, Y.C. Lee, Y.M. Darici, M. Min, J. Marcano: Phys. Rev. Lett.59, 1041 (1987) and A.A. Hezaveh, G. Jennings, D. Pescia, R.F. Willis, K. Prince, M. Surman, A.M. Bradshaw: Solid State Commun.57, 329 (1986)]. Note that, in general, non spinpolarized electron spectroscopies are not very reliable in giving yes-no answers about ferromagnetism. However once it is known that the system is ferromagnetic non spinpolarized electron spectroscopies could be very useful in determining the band structure and in particular the exchange splitting of a ferromagnetic system. It would be interesting to review some recent results of non spinpolarized angular resolved photoemission by A. Hezaveh et al. (see above) in view of the new finding that Fe/Cu is ferromagnetic
