Abstract

[Co(3 Å)/Pt(tPt)]30 (1 1 1) multilayers were prepared by molecular beam epitaxy. X-ray diffractions show clear satellite peaks around the Co/Pt fundamental peak, indicative of a good modulated structure for all Co/Pt multilayers. The optimal perpendicular magnetic properties were obtained for 6 Å < tPt < 10 Å. The effect of Pt buffer (BPt) upon the magnetic property of [Co(3 Å)/Pt(10 Å)]30/Pt(BPt) is also studied. X-ray diffractions reveal that the superlattice peaks of [Co(3 Å)/Pt(10 Å)]30/Pt(BPt) increase with increasing BPt. The Kerr rotations and polar coercivity Hc increase with increase in BPt but both saturate at about BPt = 200 Å.
