M. Kopcewicz et al., ION-BEAM MIXING - DOES IT DEPEND ON THE SUBSTRATE THICKNESS, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 127, 1997, pp. 141-144
The Ar-ion-beam mixing of Fe/Zr bilayers is studied by conversion elec
tron Mossbauer spectroscopy as a function of the thickness of the Zr s
ubstrate for doses ranging from 1 x 10(14) to 1 x 10(17) at./cm(2), Th
e results clearly show that the efficiency of mixing significantly inc
reases with increasing thickness of the Zr substrate, The mixing leads
to amorphization of the Fe/Zr system, The mixing of Fe/Zr bilayers is
compared with the mixing of Fe/Zr multilayers with corresponding thic
knesses of the elemental layers.
