Article ID: 1003-6326(2005)02-0353-05 Induced effects of Cu underlayer on (111) orientation of Fe50Mn50 thin films WANG Lei(王 蕾), WANG Feng-ping(王凤平), LIU Huan-ping(刘还平), WU Ping(吴 平... (EDX) and Auger electron spectroscopy(AES) were used to analyze the compositional distribution. It is found that Cu underlayer has an obvious induce effect on (111) orientation of Fe50Mn50 thin films......
