(a) Body-centred tetragonal (b.c.t.) structure expected in the case of the as-deposited film. (b) Trigonal structure expected for the patterned film. The b.c.t. cell is relaxed along the [10] direction. The projection in the (001) plane is shown; α′ and β′ are the values of the half diagonals. (c) Phase derivative of the first-neighbour EXAFS signal recorded in normal incidence (NI) and in grazing incidence (GI) on as-deposited Fe film (upper curves) and in perpendicular (PE), parallel (PA) and grazing incidence (GI) on the patterned Fe film (lower curves). |
