Abstract
The as-deposited and annealed Co/Ag discontinuous multilayer-like stru ctures were examined. Discontinuous Co sublayers are thought to consis t of fine superparamagnetic and ferromagnetic grains. Using the bimoda l superparamagnetic grain sizes distribution the GMR(H) dependencies w ere successfully modelled with the use of two Langevin functions simul ating the magnetization of the superparamagnetic grains.
