In this paper we investigate the origin of the giant magnetoresistance effect in atomic-sized magnetic contacts within the framework of Landauer's theory, which relates scattering to conductance in a direct way. It is believed that in magnetic contacts the scattering mechanism is spin-dependent, pro
