“…[18] devoted to magnetotransport properties of [Ni81Fe19(2)/Ag(4)]20/S multilayers. Though, this value is lower compared to that of the earlier reported for the similar systems prepared by the co-evaporation technique [17,19]. The peculiarities of [Py/Ag]8/S multilayer system is noncoincidence of field dependences of longitudinal and transverse magnetoresistance (Fig.…”

In this paper, the experimental investigation focuses on the magnetoresistive properties of nanosized film systems. Their structure changes from layered to granular due to transition from bilayer FM/NM (FM is a ferromagnetic material, NM is a nonmagnetic material) to [FM/NM]n multilayer film at a constant total thickness of samples. As ferromagnetic and nonmagnetic materials were chosen permalloy Ni80Fe20 (Py) and Ag, respectively. It was demonstrated that the shape of the field dependences of magnetoresistance depends on the number of bilayer Py/Ag. For as-deposited [Py/Ag]n/S at n = 8, 16, the transition from the antiferromagnetic ordering of magnetic moments to ferromagnetic one occurs under an external magnetic field. As a result, the resistivity of the samples reduced, and the giant magnetoresistive effect was realized. The increase of the number of bilayers repeats from 2 to 16 at the unchanged total thickness of the system leads to the growth of the magnetoresistance from 0.1 % to 0.35 %. During annealing up to 600 K, the magnetoresistive effect is reduced, but it does not disappear completely

“…At the present stage of the development of materials science, the results of studies of the physical properties of magnetically inhomogeneous film materials are of great interest. Layered structures [1][2][3], or high-entropy alloys [4] in which spin-dependent electron scattering (SDES) can be realized deserve special attention. This is due to both the study of the features of SDES and the possibility of creating functional elements with improved operational characteristics [5][6][7][8].…”

The paper presents experimental results concerning the structural-phase state, diffusion processes and magnetoresistive properties of three-layer films Сo(1 -x)Crx/Cu/Co/substrate (S) with Cr concentration in the upper layer up to 30 at. %. It is shown that the phase composition of both as-deposited and thermostabilized at the temperature of 700 K film samples with the layer thickness of 1÷30 nm corresponds to α(Co), f.c.c.(Cu) and α(Сo1 -xCrx). Studies of diffusion processes have shown that in the systems Сo(1 -x )Crx/Cu/Co/S the individuality of the layers is largely preserved both in the as-deposited state and after annealing at Tа  700 K with the penetration of Cr atoms through the Cu layer. It was found that for as-deposited and annealed at temperatures of 400 and 550 K films Сo(1 -x)Crx/Cu/Co/S with cCr  30 at. % in the upper layer, dF  20÷30 nm and dN  3÷15 nm there is an atypical character of the behavior of the field dependences of the magnetoresistance is due to the different values of the spin asymmetry coefficients of the ferromagnetic layers α
