Description
Summary:The phase composition, crystal structure, and magnetic properties of films of the ordered alloys FePd, FePt, and Fe 50 Pd 50 − x Pt x , where x = 1–10 at %, were analyzed. The spectral dependences of the magnetic rotation and optical absorption were taken. The effect of heat treatment on the crystal structure, magnetization, and coercive field strength of the ordered alloy films was studied. The influence of the degree of atomic ordering on the perpendicular magnetic anisotropy was investigated. It was shown that films of ordered FePd and FePt alloys of equiatomic composition and films of Fe 50 Pd 50 − x Pt x , where x = 1–10 at %, can serve as media for magnetic and thermomagnetic data recording and storage.
