“…In the present case the role of the Ag layers is similar, but the layer formation is somewhat different. First, in accordance with previous results [1,4] the whole 1 nm Fe layer is intermixed with the bottom B layer, as it is obvious from Fig. 3.…”

“…the normalized magnetization data are in line with the Mössbauer data. Similar trend of the HF data was observed in case of thicker Fe and B layers [1,4] and was explained by discontinuities of the Ag layer below 5 nm thickness. Since Ag does not mix with Fe and B, it acts as a barrier layer for the diffusion of B atoms deposited on top of it.…”

“…Besides that the Fe-rich alloys are more interesting from magnetic point of view, the B/Fe/Ag sequenced multi-trilayers have the advantage of a better layer morphology [3] than the Fe/B/Ag sequenced samples. In a recent publication [4] it was found that the Ag layer thickness influences the chemical mixing of Fe and B to some extent and this influence was studied in case of 2 nm B/2 nm Fe/x nm Ag sequenced multi-trilayers. The thickness of the non-alloyed Fe layer and the composition of the amorphous Fe-B interface alloy were shown to change below 5 nm Ag thickness, which was explained by discontinuities of the Ag barrier layer below 5 nm nominal thickness.…”

Top and bottom interfaces in Fe-B multilayers investigated by Mössbauer spectroscopy

Mössbauer spectroscopy is frequently applied to gain information on the interfaces in multilayers, and recently the layer sequence permutation of multitrilayers was suggested to enhance its capability to characterize bottom and top interfaces of a given layer. The sequence permutation, however, in the investigated Fe-BAg multitrilayers affected the waviness of the layers as well, and the results hinted at the possibility that although Ag does not mix with Fe and B, the Fe-B amorphous alloy formation is influenced by the layer-sequence-dependent morphology of the Ag layers in the multitrilayers. Now we examine the interface mixing of Fe and B in the case of a fixed layer sequence and varying thickness of the Ag layers in [2 nm B/2 nm Fe/x nm Ag] 4 , 0.2 x 10, multitrilayer samples and in B/Fe/B and B/Fe/Ag trilayers. Below x = 5 nm, both the ratio of the nonalloyed Fe layer and the average hyperfine field of the amorphous Fe-B interface compound change. The variation is attributed to thickness-dependent discontinuities of the Ag layers. Ag acts as a barrier to the diffusion of B from the top side and thus the discontinuities lead to a varying ratio of top and bottom interfaces. The evaluation based on this model shows that the "B on top of Fe" interface has an average B concentration about 11 at. % higher than the "Fe on top of B" interface. A slightly smaller difference, 6 at. %, is deduced from low-temperature conversion electron Mössbauer spectroscopy measurements of the trilayers.
