摘要
基于气体聚集（ＧＡ）形成团簇的过程，利用双束蒸发共沉积方法，在室温下成功地制备了Ｆｅ－Ｃｕ纳米磁性包埋团簇样品。对样品的ＴＥＭ／ＥＤ分析表明，平均直径为２０ｎｍ左右的Ｆｅ团簇被Ｃｕ原子所包裹，形成了以Ｆｅ团簇为芯，Ｃｕ原子为壳的良好的芯－壳式包埋结构。
Based on Gas-Aggregation (GA) process, nanometer size Fe-Cu embedded clusters are produced by bi-beam co-evaporation method at room temperature. TEM/ED investigation shows that Fe clusters about 20urn in diameter are embedded in Cu matrix, and the core--shell structure with Fe cluster being the core and Cu atoms being the shell is well formed in so-prepared specimens.
