Epitaxial Fe/MgO/Fe(001) magnetic tunnel junctions grown by Molecular Beam Epitaxy have been studied by using spatially resolved Electron Energy Loss Spectroscopy (EELS). The structure, the chemical composition as well as the bonding variations across the interfaces were investigated up to the atomic scale.
