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. At deposition of films by methods of physical condensation to supervise an initial stress in Fe50Pt50 layer of Fe50Pt50/Ме/Fe50Pt50 film composition where Me - (Au, Ag, Cu) is possible by change of a thickness, quantity of additional layers of metal, their location, substrate type (SiO2(100 nm)/Si(001) or Al2O3), speed of heating and annealing atmosphere (vacuum, nitrogen, Ar + 3 at. % H and H2). Practical recommendations concerning the control of processes of chemical ordering are developed at solid-phase reactions А1 into L1о at the expense of change of level and a sign on mechanical stress in films. Nanoscale films on the basis of FePt and FePd with the lowered temperature of formation of L1о phase and the raised thermal stability of phase composition and structure, and also the improved magnetic properties higher Hc,, Ms, Mr,, orientation of easy с-axis magnetization with perpendicular, or in parallel a film plane are received. The application of these films as magnetic recording medial allow increase the magnetic recording density by HAMR method and stability of storage of the information.
