Structural and Magnetic Properties of Electrodeposited Co/Cu Multilayers



M Shima, L Salamanca-Riba, Thomas P. Moffat, Robert D. McMichael


A series of [Co(x ML)/Cu(17 ML)]100 multilayers were electrodeposited on Si(0 0 1) substrates covered with Cu seed layers. Magnetic hysteresis loops for lms with x 2 ML have sigmoidal shapes and the temperature dependence indicates a superparamagnetic behavior of the ultrathin Co layers. This behavior appears to be due to a discontinuity of the Co layers in the multilayer structure. In contrast, lms with x 2ML have rectangular loops. In-plane four-fold symmetry is observed for x 4ML, which re ects the magnetocrystalline anisotropy of the multilayers. The giant magnetoresistance e ect is observed for x 2ML.
