Modification of Fe/Cu multilayers under 400 keV Xe20+ irradiation
Two kinds of Fe/Cu multilayers with different modulation wavelength were deposited on cleaved Si(100) substrates and then irradiated at room temperature using 400 keV Xe20+ in a wide range of irradiation fluences.As a comparison,thermal annealing at 300-900℃ was also carried out in vacuum.Then the samples were analyzed by XRD and the evolution of crystallite structures induced by irradiation was investigated.The obtained XRD patterns showed that,with increase of the irradiation fluence,the peaks of Fe became weaker,the peaks related to Cu-based fcc solid solution and Fe-based bcc solid solution phase became visible and the former became strong gradually.This implied that the intermixing at the Fe/Cu interface induced by ion irradiation resulted in the formation of the new phases which could not be achieved by thermal annealing.The possible intermixing mechanism of Fe/Cu multilayers induced by energetic ion irradiation was briefly discussed.
