摘要：

We present transport and structural data from epitaxial (100) and (111) Au/Fe superlattices grown by molecular beam epitaxy. From their analysis, we conclude that an electron channeling mechanism, due to strong specular reflection of the; minority spin carrier at the Au/Fe interfaces, is responsible for the high conductivity in the (100) superlattices.
