“…A coercive field of approximately 20 Oe has been reported by Wu et al 23 and of approximately 7.5 Oe by O'Brien, Drobay, and Tonner. 14 The spin-reorientation transition for Ni/Cu͑100͒ has been observed by Wu et al 23 and Bochi et al 24 to occur between 7 and 8 ML of Ni. The saturation magnetization below the transition is approximately 5 rad, 23 in reasonable agreement with our finding.…”

Magnetic properties of ultrathin fcc Fe overlayers on Ni/Cu͑100͒ have been determined to study the influence of a magnetic interface. Three regions of different magnetic behavior are distinguished by magneto-optic Kerr ellipsometry, in line with previous studies of Fe/Co/Cu͑100͒ and Fe/Ni/Cu͑100͒. These magnetic states are closely related to the film structure. Above 10 monolayers ͑ML͒, the iron films are homogeneously magnetized and adopt the bcc phase. Very thin films up to 2.5 ML are homogeneously magnetized as well but show an fcc structure in conjunction with a (4ϫ1) reconstruction. The most complex magnetic properties characterize Fe films between 5 and 10 ML. In this thickness range the iron films are not homogeneously magnetized. Instead ferromagnetism is only observed at the Fe film surface and the Fe/Ni film interface. The surface magnetization is apparently correlated with an enlarged atomic volume at the surface and a (2ϫ1) surface reconstruction. Additionally, the magnetic Ni substrate induces ferromagnetic order in the Fe film at the Fe/Ni interface. The coupling of the two ferromagnetic portions of the film shows a strong temperature dependence. This is attributed to the temperature dependence of the bilinear and biquadratic exchange coupling. At low temperature an antiferromagnetic coupling between the two ferromagnetic portions is observed. With increasing temperature this is followed by a canted spin arrangement and finally a ferromagnetic coupling. ͓S0163-1829͑99͒07041-1͔

“…As a matter of fact, strong chemical reactivity generally occurs even at low temperatures leading to polycrystalline films. As an exception, copper is the only example of metal epitaxy and Cu layer has been extensively used as seed layers for subsequent growth of other systems such as Cu/Ni multilayers [2,3]. Hydrogenation of Si by immersing in HF baths seems to inhibit copper diffusion in Si, and therefore limits copper silicide formation and allows the achievement of Cu(0 0 1) films epitaxially grown [4].…”

“…It has been demonstrated that such types of systems can exhibit a perpendicular magnetization in a wide range of thicknesses ͓10-60 Å of Ni for vacuum /Ni/Cu/Si͑001͒ and 20-135 Å of Ni for Cu/Ni/Cu/Si͑001͔͒. 6,8 Various domain sizes have been observed 6 in Ni/Cu/Si͑001͒ ML capped by 20 Å of Cu. Measurements have shown that a 10.2 ML film of Ni has a perpendicular orientation of the magnetization vector.…”
