Abstract

The magnetic properties of a series of electrodeposited [Co(x ML)/Cu(17 ML)]100 multilayers have been examined as a function of the cobalt layer thickness. The multilayers were grown on Si(100)covered with a highly textured Cu(100) seed alyer. Films with a cobalt layer thickness less than x 1.7 ML the lateral length scale becomes large enough to stabilize ferromagnetism and the giant magnetoresistance effect is observed. The influence of magneticrystalline anisotropy is not apparent until 2.5 > x > 3.7 ML. The coercivity increases between 1.6 and 9 ML reflecting the combined influence of the magnetocrystalline anisotropy and surface roughness.
