“…Alloy composition and grain size could significantly affect the atomic magnetic moment (AMM) and plays a decisive role in influencing it for fcc structured MNCPs and at stoichiometry of Fe and Pt, the AMM reaches a peak value. A shell-core model is proposed [463] and it could well explain the positive proportion between the AMM and the grain size observed in the experiments.…”

“…The complete system of extralines and baselines (001), (110), (111), (200), (002), (112), (202), (310), ( 222) is formed in the interval Ta = 620 -820 K. The intensity of the ordering process can be deduced from the rate of increase of the intensity of the line (111) as the line with the highest intensity [8]. This phenomenon is observed both in continuous film samples [9][10][11][12][13][14][15] and in monoatomic multilayers, in which the FePt layer has a thickness d  1 nm [16]; ultrathin islet FePt films with an effective thickness d = 1 -10 nm [17]; FePt thin films (d = 10 nm) [18]; granular FePt films deposited in the SiO2 matrix [19,20] or in the Al2O3 matrix [21].…”

The paper shows the experimental results of the study of magneto - optical properties and phase composition of thin films and multilayers based on Fe and Pt. Samples were obtained in a high-vacuum chamber (10–8 Pa) by layer-by-layer deposition from pots at room temperature. It has been shown that FCC solid solution of FePt is formed already in the process of deposition on the substrate (sital plates). Depending on the concentration of the atoms of the components in the unannealed samples, three phases can be formed: (i) s.s. Fe(Pt); (ii) Fe3Pt; (iii) FePt. The first sign of the beginning of ordering in the FCC phase of FePt should be considered the appearance of superreflections in the form of lines (001) and (002) during heat treatment. Depending on the total thickness of the multilayer or individual layers, the annealing temperature at which extrareflexes appear can vary in the range of 300–570 K. All the samples obtained have a low coercivity (0.25 - 0.4 mT). Magneto-optical studies have shown that an increase in the content of the non-magnetic component decreases the main magnetic characteristics. However, In [Fe(3)/Pt(3)]n/S multilayers with the number of repeatable elements from 2 to 8 an increase in the main magnetic parameters is observed compared with bilayer films at the same effective thickness.
