Abstract
We aimed to study the local structure change as amorphous FePd multilayer transformed into the ordered face-center-tetragonal FePd under annealing. [Fe (2 nm)/Pd (2 nm)]30 multilayer on MgO [001] substrate were prepared using a home-built magnetron sputtering system. As made samples were annealed at 2, and 10 hours at 700 ℃ in high vacuum condition. From the EXAFS analyses for the nearest scattering paths of Fe-Fe and Fe-Pd, we found that despite the inversive change in the lattice parameters c and a, the c/a ratio and cell volume of the FePd became smaller which demonstrates a more compact structure of FePd as an effect of longer annealing time.
