Abstract

Commercially available track-etched polyester membranes were used as templates to electrodeposit Co-Ni-Cu/Cu multilayered nanowires, giving room-temperature current perpendicular to plane (CPP) giant magnetoresistance (GMR) values of up to similar to 12%. In contrast to similar nanowires electrodeposited in track-etched polycarbonate membranes, the GM R: obtained in multilayered nanowires electrodeposited in the polyester membranes increased with decreasing Cu-layer thickness t(Cu) for t(Cu) in the 2-7 nm range, indicating a lack of ferromagnetic coupling through pinholes, etc. Transmission electron micrographs showed clear evidence for smooth, parallel layer interfaces in the nanowires.
