摘要

The formation of the atomically ordered L1(0)-FePd structure during the solid-state reaction in Fe/Pd bilayer thin films is in situ investigated by electron microscopy and electron diffraction analysis. The initial iron and palladium layers were mainly coherently oriented crystallites with the orientation relationship alpha-Fe (001)[110] || Pd(001)[100]. It is established that the solid-state reaction between the iron and palladium layers upon heating at a rate of 4-8A degrees C/min starts with the formation of the FePd solid solution at 390A degrees C; at 430A degrees C, the formation of the atomically ordered L1(0)-FePd structure is observed. It is shown that at the low heating rate (4-8A degrees C/min), the L1(0)-FePd structure with the [001] orientation relative to the film plane forms, while at the high heating rate (50A degrees C/min) it forms with the [100], [010], and [001] orientations.
