摘要：

We report the observation of oscillatory interlayer coupling for a series of Fe50angstrom[Co12angstrom-Cutangstrom]15Cu50angstrom samples sputtered on glass substrates. The antiferromagnetic (AF) maxima are observed for t = 9 and 20 A. The particularities of our samples are their very small grain size (approximately 20 angstrom) without any preferential orientation and the sharpness of their interfaces (approximately 1 angstrom). These characteristics are favorable to strong magnetoresistive effects which exceed 40% at 300 K and 90% at 4.2 K for our best samples. Our results must be confronted by theoretical models that are only valid in the case of ideal single-crystals.
