<Peter Grünberg> coauthored experiments revealing a large dependence of <electrical resistance> on the relative orientation of magnetic layers. In <iron>-<chromium>-<iron> structures, an antiparallel arrangement of the iron-layer <magnetization> gave higher <electrical resistance> than a parallel arrangement. The effect grew in structures containing more magnetic layers and substantially exceeded ordinary anisotropic <magnetoresistance>. This connects magnetic configuration with electrical readout and helped establish <giant magnetoresistance> as a basis for magnetic sensing.<Enhanced magnetoresistance in layered magnetic structures with antiferromagnetic interlayer exchange by G. Binasch and others>[Physical Review B 39, 4828 (1989), abstract]{ref}
