Аннотация: This paper reports on the results of investigations into the temperature and spectral dependences of the magnetic circular dichroism in Dy1-xNix-Ni bilayer films prepared through thermal sputter deposition of components under ultrahigh vacuum. The distribution of the components over the layer thickness is examined by Auger spectroscopy. The nickel content x in Dy1-xNix layers varies from 0.005 to 0.06. It is shown that, in the temperature range 80-300 K, the contribution made to the magnetic circular dichroism by a Dy1-xNix layer in a bilayer film with a nickel content higher than the threshold value is approximately equal to the magnetic circular dichroism observed in an isolated Dy1-xNix film at temperatures below the temperature of the phase transition to a ferromagnetic state (similar to100 K). This phenomenon is explained by magnetic ordering in theDy(1-x)Ni(x) layer of the bilayer film due to the combined effect of two factors, namely, the incorporation of nickel into a dysprosium layer and the presence of a continuous nickel sublayer in the film.

Аннотация: The transmittance D(omega), reflectance R(omega), and dispersion omega(k) are investigated for waves of various nature propagating through a one-dimensional superlattice (multilayer structure) with arbitrary thickness of the interlayer boundary. The dependences of the band gap widths Deltaomega(m) and their positions in the wave spectrum of the superlattice on the interlayer boundary thickness d and the band number m are calculated. Calculations are performed in terms of the modified coupled-mode theory (MCMT) using the frequency dependence of R(omega), as well as in the framework of perturbation theory using the function omega(k), which made it possible to estimate the accuracy of the MCMT method; the MCMT method is found to have a high accuracy in calculating the band gap widths and a much lower accuracy in determining the gap positions. It is shown that the m dependence of Deltaomega(m) for electromagnetic (or elastic) waves is different from that for spin waves. Furthermore, the widths of the band gaps with m = 1 and 2 are practically independent of d, whereas the widths of all gaps for m 2 depend strongly on d. Experimental measurements of these dependences allow one to determine the superlattice interface thicknesses by using spectral methods. (C) 2004 MAIK "Nauka/Interperiodica".

Solid-phase reactions and the order-disorder phase transition in thin films / V. G. Myagkov [et al.] // Tech. Phys. - 2001. - Vol. 46, Is. 6. - P. 743-748, DOI 10.1134/1.1379645. - Cited References: 28 . - ISSN 1063-7842

Аннотация: A comparative analysis was carried out of the initiation temperatures of solid-phase reactions in bilayer solid films and the Kurnakov temperatures of the phases forming in the reaction products. It has been shown that in superstructures where ordering is usually observed, the Kurnakov temperature coincides with the initiation temperature of the solid-phase reactions if no other solid-phase structural transformation precedes the order-disorder phase transition in the state diagram. A rule was proposed by which pairs of films capable of entering into solid-phase reactions and their initiation temperatures can be determined. (C) 2001 MAIK "Nauka/Interperiodica".

Аннотация: The paper presents the results of ferromagnetic resonance studies of three-layer magnetic films, where the magnetic layers are amorphous magnetically soft CoP layers, and the intermediate non-magnetic spacer is amorphous NiP layer. We found that, regardless of the nonmagnetic layer thickness, the interlayer interaction is ferromagnetic. Perpendicular anisotropy forms at the interface between the CoP and NiP layers. It is reasonable to suppose that the interlayer interaction is long-range, what is not typical for systems with metallic non-magnetic spacers.

Аннотация: A sequence of phases forming during the solid-phase reaction in Al/Pt bilayer thin films has been investigated by in situ electron diffraction. It is shown that the amorphous PtAl2 phase forms first during the solid-phase reaction initiated by heating. Upon further heating, PtAl2, Pt2Al3, PtAl, and Pt3Al crystalline phases sequentially form, which is qualitatively consistent with an effective formation heat model. The content of phases forming during the reaction has been quantitatively analyzed and the structural phase transformations have been examined.

Аннотация: The self-propagating high-temperature synthesis in the two-layer and multilayer Pt / Co(001) thin films has been investigated. It is shown that the initiation of the synthesis occurs at temperatures of 770-820 K. After the synthesis in the two-layer film samples, the PtCo(001) disordered phase exhibits an epitaxial growth at the interface between cobalt and platinum layers. In the multilayer Pt/Co(001) thin films, the self-propagating high-temperature synthesis also brings about the formation of the PtCo(001) disordered phase on the MgO(001) surface. Further annealing at a temperature of 870 K for 4 h results in the transition of the PtCo(001) disordered phase to the ordered phase. Rapid thermal annealing of the Pt/Co(001) multilayer films at a temperature of 1000 K leads to the formation of the CoPt3 phase. The magnetic characteristics change in accord with the structural transformations in Pt/Co film samples. (C) 2000 MAIK "Nauka/Interperiodica".

Аннотация: The solid-phase synthesis of the Co(7)Sm(2) and Co(17)Sm(2) magnetically hard phases in Co/Sm/Co(110) epitaxial film systems has been experimentally investigated. The Co(7)Sm(2) phase is first formed at the Sm/Co interface at a relatively low (similar to 300 degrees C) temperature. As the annealing temperature increases to similar to 450 degrees C, the Co(17)Sm(2)(110) phase grows epitaxially on the Co(7)Sm(2)(110) phase. The saturation magnetization and biaxial anisotropy constant in the samples vary with the formation of the Co(7)Sm(2) and Co(17)Sm(2) phases. Investigations of the solidphase synthesis in the nanofilms reveal the existence of a new structure phase transition at 300 degrees C in the Co-Sm system with a high cobalt content.

Аннотация: Three-layer Co/Ge/Co films have been studied using electron magnetic resonance. It has been established that the resonance spectrum of the film is a superposition of two Lorentzian lines. It has been found that the anisotropy induced at the cobaltaEuro'germanium interface makes the main contribution to the resonance spectrum and determines its features. The temperature dependences of the anisotropy field and the parameters of the interlayer exchange have been measured. The interlayer interactions exhibit an antiferromagnetic character and have been explained in terms of a model similar to the description of superexchange in magnetic dielectrics.

Аннотация: We investigate the dynamic susceptibility and one-dimensional density of states in an initially sinusoidal superlattice containing simultaneously 2D phase inhomogeneities simulating correlated rough-nesses of superlattice interfaces and 3D amplitude inhomogeneities of the superlattice layer materials. The analytic expression for the averaged Green's function of the sinusoidal superlattice with two phase inhomogeneities is derived in the Bourret approximation. It is shown that the effect of increasing asymmetry in the peak heights of dynamic susceptibility at the Brillouin zone boundary of the superlattice, which was discovered earlier [15] upon an increase in root-mean-square (rms) fluctuations, also takes place upon an increase in the correlation wavenumber of inhomogeneities. However, the peaks in this case also become closer, and the width and depth of the gap in the density of states decrease thereby. It is shown that the enhancement of rms fluctuations of 3D amplitude inhomogeneities in a superlattice containing 2D phase inhomogeneities suppresses the effect of dynamic susceptibility asymmetry and leads to a slight broadening of the gap in the density of states and a decrease in its depth. Targeted experiments aimed at detecting the effects studied here would facilitate the development of radio-spectroscopic and optical methods for identifying the presence of inhomogeneities of various dimensions in multilayer magnetic and optical structures.
