The formation of nanosized hard magnetic FePt films alloyed by Ag, Au, Cu for increase of magnetic recording density

підвищення щільності магнітного запису

New principles of stable nanoscale hard magnetic FePt films formation with ordered L10(FePt) phase are created by the way of regulation the rate of solid state reactions by using additional layers of alloying elements (Ag, Au, Cu) as regulators of diffusion flows. It is reached the decrease of the hard magnetic L10(FePt) phase formation temperature on 100 K due to extra driving force at the creation of additional interfaces and stress state that accelerate the diffusion processes of ordering.
