Abstract
Single-crystalline FePd(001) 1000-Angstrom-thick films were grown at 5 00 degrees C by codeposition in an UHV sputtering system. It is found that both the crystalline structure and therefore the magnetic propert ies strongly depend on the Pt buffer layer thickness. The films grown on Pt(100) layers 50 Angstrom thick and thinner do not exhibit clear c hemical order and show in-plane magnetic anisotropy. FePd grown on thi cker Pt buffers adopts a fct structure accompanied by a strong chemica l ordering, leading to a perpendicular magnetic anisotropy. (C) 1997 A merican Institute of Physics.
