Abstract
The hard magnetic L 10 ordered phase formation in thin Pd and Fe bilayers prepared on MgO (001) substrate has been investigated by transmission electron microscopy using in situ annealing. The structures of as-deposited Fe/Pd and Pd/MgO interfaces were characterized by high-resolution transmission electron microscopy. Fast intermixing of Fe and Pd layers and immediate L 10 phase formation within the alloyed area was found at 673 K. The high-resolution observations indicated that the ordered region of the L 10 -FePd phase was formed in dispersed areas without a predetermined nucleation site. At 773 K, the growing ordered areas occasionally formed antiphase boundaries between the adjacent parts. The ordered L 10 -FePd thin layer contained translational domains with tetragonal c axis perpendicular to the substrate.
