The scientific foundations for the accelerated formation of nanoscale, thermally stable films based on FePd, FePt with a magnetic-hard L1о phase for use as a medium of high-density magnetsc recording have been created. The influence of the chemical and mechanical factor of hydrogen action on the phase composition and structure, as well as the physical factor of the effect on the electronic structure of nanoscale films based on FePt and FePd doped with Au, Ag, Cu, and their magnetic properties was estimated and taken into account.
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.
