Kubo formalism is used to calculate the magnetoresistance due to magnetization rotation in a structure consisting of two magnetic films separated by a nonmagnetic layer. In the approximation of a uniform relaxation time for each layer, the oscillatory term in magnetoresistance corresponds to the oscillation period which depends on the potential barriers at the interfaces. This period is longer than the oscillation period observed in the coupling parameter.
