我们曾报道了在同一剂量下的~(57)Fe离子注入铜随退火温度变化的特性,观察到注入铁离子所处的三种不同位:固溶态的孤立铁原子、具有二个或更多铁原子结合在一起的固溶态原子组团(Cluster)和γ-Fe夹杂相;经一定温度退火后,固溶态的铁原子和γ-Ee分别通过凝聚和相变转变成具有体心立方结构的α-Fe;在600℃退火后α-Fe全部消失转变成固溶态铁。本文着重报道不同的~(57)Fe注入剂量对铁原子不同位的强度和它们的超精细参数的影响以及它们随不同退火温度的变化关系。
We reported the variation of copper with annealing temperature of ~ (57) Fe ion implanted at the same dose. We observed three different sites where Fe ions were implanted: solute isolated solute atoms with two or more After annealing at a certain temperature, the solid solution of iron atoms and γ-Ee are transformed into the core with the body-centered cubic Structure of α-Fe; annealed at 600 ℃ α-Fe all disappear into solid solution of iron. This article focuses on the effects of different doses of ~ (57) Fe on the intensities of different iron atoms and their hyperfine parameters and their relationship with different annealing temperatures.
