摘要

We discuss the magnetic-field dependence of the magnetoresistance MR(H) of magnetic multilayers for samples in the as-prepared state (meaning the first time the magnetic field is swept), pointing out the importance of the electron-scattering mean-free path. We show that the value of MR(0) in the as-prepared state is related to MR(H) data for field-swept samples (meaning samples for which the magnetic field has been swept back and forth). We use this relationship to obtain the value of MR(0) for an as-prepared sample. Our prediction agrees with the data.
