Abstract
The γ-Fe formation in epitaxial Cu(0 0 1)/Fe(0 0 1) bilayers with the annealing temperature increasing has been studied. Using Mössbauer spectroscopy, X-ray diffraction, and magnetic analysis, structural and chemical characterization of the interface between cooper and iron layers has been performed. After annealing at 850 °C and subsequent cooling to room temperature, paramagnetic γ-Fe(0 0 1) precipitates with an average size of 30 nm coherent to a Cu(0 0 1) matrix form. Conditions of intermixing and the γ-Fe formation at the Cu/Fe interface are explained in terms of the solid-state synthesis in thin films. Specific features of the martensitic transition γ↔α are discussed.
