研究了CoFe合金薄膜作为Co基垂直记录介质的软衬层（SUL）。研究了晶种层的组成、晶相的形成、织构的形成以及磁性能的影响。沉积在Ta/Pd种子层上的薄膜比沉积在玻璃衬底或Ta种子层上的薄膜具有更好的FCC（111）织构。当沉积在Ta/Pd种子层上时，磁性能也更好。在这些晶种层上，发现15at%的Fe浓度适合于FCC相的形成。用CoFe SUL制备了纳米晶。CoFe SUL的噪声是有待解决的挑战之一。
CoFe alloy thin films were studied with the intention of potential use as a soft underlayer (SUL) for Co-based perpendicular recording media. The effect of composition and the effects of seedlayers on the formation of crystalline phase and crystallographic texture and the magnetic properties were investigated. Films deposited on Ta/Pd seedlayer were found to have a good FCC(111) texture than those deposited on glass substrates or on Ta seedlayers. The magnetic properties were also better when deposited on Ta/Pd seedlayers. On these seedlayers, Fe concentration of 15at% was found to be suitable for the formation of FCC phase. Disks were prepared with CoFe SULs. The noise of CoFe SUL is one of the challenges to be solved.
