Abstract
A very thin Cu (~1 nm) buffer layer on Si(110) is enough to induce Ni80Fe20/Fe60Mn40 (111) epitaxial growth. The film surface roughness increases with increasing Cu thickness. The crystallinity improves as the Cu buffer thickness increases. The uniaxial anisotropy of the pinned Ni80Fe20 was greatly enhanced in the samples with thick Cu (>10 nm). This reflects the great effect of film crystallinity on exchange anisotropy
