Giant magnetoresistance in antiferromagnetic co/cu multilayers grown on kapton

Multilayers of Co/Cu, sputter deposited onto thin kapton films, display very large room-temperature magnetoresistance, almost as large as that found in similar structures prepared on silicon wafers. Such flexible structures suggest a number of intriguing technological applications. Plane-view and cross section transmission electron micrographs reveal a high degree of structural order with grains extending over several hundred angstrom with sharp grain boundaries. © 1992 The Japan Society of Applied Physics.
