摘要
Remote imaging of giant magnetoresistance (GMR) involves the use of an infrared charge coupled device camera to remotely sense changes in the materials' emissivity on a spatial scale when a magnetic field is applied. The technique has previously allowed quick and remote imaging of GMR in multilayered and spin-valve systems with a spatial resolution of 200 mu m. Here, images of the GMR in CoFe/Cu multilayers are presented with an improved spatial resolution of 30 mu m. The improved resolution demonstrates further the potential of the technique for in situ whole wafer characterization of GMR, and the study of GMR in patterned multilayered media where spatial resolution is desired.
