Abstract
We studied the effect of interfaces character in 57Fe/Au thin layers on iron hyperfine parameters using Mössbauer spectroscopy. Four samples of bilayers (57Fe covered by Au) were prepared on MgO substrate by pulsed laser deposition (PLD) with varying 57Fe layer thickness (∼10–95 nm), covered by Au layer with constant thickness of ∼8.7 nm. Mössbauer spectra were acquired in transmission and conversion electron geometry. The hyperfine parameters of α–Fe layer, Fe/Au and MgO/Fe interfaces were determined.Keywords
