摘要

High-quality Co(11»00)/Cr(211) superlattices have been successfully prepared and characterized. Excellent heteroepitaxial (hcp/bcc) growth of Co/Cr superlattices was evidenced by fine streaks in reflection high-energy electron diffraction and superlattice satellites in x-ray diffraction. The magnetic hysteresis loops and magnetoresistance (MR) show strong crystalline-induced magnetic anisotropy and a field-direction-dependent MR effect. We have observed large transverse (IH) MR up to about 18% with magnetic field H along the in-plane hard axis Co[112»0], and current I along the in-plane easy axis Co[0001], and small longitudinal MR (0.8%) for IHCo[112»0]. On the other hand, negligible longitudinal and transverse MRs (<0.1%) were observed for HCo[0001].
