C. A. Huang Department of Physics, National Cheng-Kung University, Tainan, Taiwan Y. Liou, Y. D. Yao, W. T. Yang, C. P. Chang, and S. Y. Liao Institute of Physics, Academia Sinica, Taipei, Taiwan Y. M. Hu Department of Physics, National Cheng-Kung University, Tainan, Taiwan Received 14 August 1995 High-quality Co(11-bar00)/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 (IperpH) MR up to about 18% with magnetic field H along the in-plane hard axis Co[112-bar0], and current I along the in-plane easy axis Co[0001], and small longitudinal MR (~0.8%) for I||H||Co[112-bar0]. On the other hand, negligible longitudinal and transverse MR's (<0.1%) were observed for H||Co[0001]. ©1995 The American Physical Society URL: http://link.aps.org/abstract/PRB/v52/pR13110 DOI: 10.1103/PhysRevB.52.R13110 PACS: 75.30.Gw, 75.50.Rr, 75.70.Fr ------------------------------------------------------------------------ [Add to article collection] View Page Images , Figure Images or PDF (891 kB) [ Previous article | Next article | Issue 18 contents ] ------------------------------------------------------------------------ References (Reference links marked with [dot] may require a separate subscription.) 1.
