摘要
[Co(3Angstrom)/Pt(t(Pt))](30) (111) 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 Angstrom < t(Pt) < 10 Angstrom. The effect of Pt buffer (B-Pt) upon the magnetic property of [Co(3 Angstrom)/Pt(10 Angstrom)](30)/Pt(B-Pt) is also studied. X-ray diffractions reveal that the superlattice peaks of [Co(3 Angstrom)/Pt(10 Angstrom)](30)/Pt(B-Pt) increase with increasing, B-Pt. The Kerr rotations and polar coercivity H-c increase with increase in B-Pt but both saturate at about B-Pt = 200 Angstrom. (C) 2002 Elsevier Science B.V. All rights reserved.
