It is shown that the method of bombardment of a nanothick vacuum-condensed metallic substance with low-energy ions is a promising tool for the purposeful formation of such gradient distributions of structural-phase states that provide new properties. New methodological approaches have been developed in the structural analysis of nanoscale materials using synchrotron radiation (with a photon flux density by 12 orders of magnitude, and an exposure duration 150 times shorter than provided by traditional methods of X-ray structural analysis).
Scientific bases of formation nanoscale thermally stable films on the basis of FePd, FePt with hard magnetic L1о phase are created. The new scientific approach concerning application of mechanical stress in nanoscale films on the basis of FePt and FePd for management in temperature of chemical ordering, is offered by formation of phase composition, structure and magnetic properties.
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.
