摘要：

We report on giant magnetoresistance (GMR) of Fe-cluster-dispersed Ag films. Composite thin films with a thickness of about 2000 angstrom and the compositional ratios Fe/Ag = 20/80, 33/67 and 45/55 have been produced by an ionized cluster beam (ICB) technique. Measurements of X-rav diffraction, transmission electron microscope, magnetization and magnetoresistance display the following salient features: (1) GMR is observed without any heat treatment of the samples, (2) GMR of about 25% is obtained for Fe/Ag = 33/67, and (3) MR is not saturated even in a magnetic field of 140 kOe for these specimens, although the magnetizations are saturated in a magnetic field of about 3 kOe.
