2005年5月24日收到;2005年11月29日收到改稿;在室温下,我们在Cu 001衬底上的单层ML Pd上生长了外延Co薄膜。Pd膜采用脉冲激光沉积法生长,Co膜采用热沉积法生长。Co在1ml Pd/ cu001体系上的逐层生长模式可以持续到至少11ml的Co,而在Pd 001基质上只能生长4ml的Co。这是由于与Pd 001衬底上的Co膜相比,Pd/Cu 001体系上的Co膜的晶格不匹配度降低。在磁光克尔旋转数据的基础上,讨论了Co-Pd界面对磁性和磁光响应的影响。DOI: 10.1103/PhysRevB.73.035429 PACS编号:78.20。Ls, 75.70。Cn, 75.70.Ak
Received 24 May 2005; revised manuscript received 29 November 2005; published 25 January 2006We have grown epitaxial Co films on single monolayers ML of Pd on Cu 001 substrates at room tem-perature. The interlayers of Pd were grown by pulsed laser deposition whereas the Co films were prepared bythermal deposition. A layer-by-layer growth mode of Co on the 1 ML Pd/Cu 001 system continues up to atleast 11 ML of Co in contrast to the 4 ML of Co on the Pd 001 substrate. This is due to a reduced latticemismatch for the Co films on the Pd/Cu 001 system in comparison to the Co films on the Pd 001 substrate.On the basis of magneto-optical Kerr rotation data we discuss the effect of the Co-Pd interface contribution tomagnetism and to the magneto-optical response.DOI: 10.1103/PhysRevB.73.035429 PACS number s : 78.20.Ls, 75.70.Cn, 75.70.Ak
