【Abstract】 The NiFe/Cu and NiFe/Mo multilayers (MLs) were deposited by dc magnetronsputtering. The magnetoresistance and the magnetism of the MLs were measured, and the crosssectional images of the NiFe/Cu M Ls were analyzed by transmission electron microscopy (TEM). Thethree peaks of MR ratio for NiFe/Cu MLs were observed at room temperature as the thickness of Culayer was varied, while no MR of NiFe/Mo MLs was found with the varied thicknesses of Mo. Thedependence of GM R on interface structure was studied.更多还原
