Ar ion irradiation in Au/Fe multilayers

We have investigated Ar ion irradiation effects on the physical properties of Au/Fe multilayers (MLs). The Au/Fe MLs prepared in the different batches under the same condition show different physical properties, which have be en observed by conversion electron Mossbauer spectroscopy (CEMS), The 400 k eV Ar ion irradiation at the dose of 3 x 10(13)-2.56 x 10(16) ions/cm(2) in duces a change of the magnetic and structural properties of the Au/Fe MLs, depending on the as-deposited state and the ion dose. The ion irradiation i s an important means of post-treatment of metallic multilayers. (C) 1999 El sevier Science B.V. All rights reserved.
