RESUMO

Magnetic properties of electrodeposited of chromium and chromium-cobalt thin films on cooper substrate were investigated. The samples were prepared without introduction of additives. This procedure following to samples with granular structure. Magnetization measurements as a function of applied magnetic field and temperature show that the magnetic behavior exhibit a strong dependence on the thickness of the electrodeposited film and the samples presents a superparamagnetic behavior associated with the formation of ferromagnetism surface.
