The magnetic properties of sputtered Co/Pb multilayers have been studi
ed. When d(Pb) < 23 Angstrom, a perpendicular magnetic anisotropy (PMA
) is found to increase with decreasing Pb thickness. The PMA is attrib
uted mainly to the magnetocrystalline anisotropy. The observation of s
pin-wave resonance, and low in-plane remanence ratio suggests the exis
tence of interlayer coupling in this system. (C) 1998 Elsevier Science
