Abstract

This paper reports the influence of the deposition temperature and the wavelength of the periodicity on the effective interdiffusivity, microstructure, and magnetic properties of annealed [Fe/Pt](n) multilayer films (MLs). It was found that both the deposition temperature and periodicity of [Fe/Pt](n) MLs have a significant influence on the effective Fe-Pt interdiffusivity, microstructure, and magnetic properties of the annealed films. It was also observed that the magnitude of the effective interdiffusion coefficient, the L1(0) grain size, and the long-range order parameter were positively correlated. This result suggests that nonequilibrium reaction kinetics are desirable for the reduced temperature formation of the L1(0) FePt phase.
