Tailoring magnetic properties of multicomponent layered structure via current annealing in FePd thin films.

ABSTRACT: Multicomponent layered systems with tailored magnetic properties were fabricated via current annealing from homogeneous Fe₆₇Pd₃₃ thin films, deposited via radio frequency sputtering on Si/SiO2 substrates from composite target. To promote spontaneous nano-structuring and phase separation, selected samples were subjected to current annealing in vacuum, with a controlled oxygen pressure, using various current densities for a fixed time and, as a consequence, different phases and microstructures were obtained. In particular, the formation of magnetite in different amount was observed beside other iron oxides and metallic phases. Microstructures and magnetic properties evolution as a function of annealing current were studied and interpreted with different techniques. More
