Crystalline Structure and Physical Properties of High-Entropy Film Alloys

Concentration Effects in the Electronic Properties of High-entropy Film Alloys

“…1 shows the calculated data for four-and fivecomponent film alloys, which at all values x are threeor four-component equiatomic systems. Note that the resistivity values agree well with similar data for fivecomponent film alloys [6,7]. To some extent, this can satisfy the correctness of our hypothesis about the additivity of the resistivity of single-component films, on the basis of which HEA is formed.…”

“…Since this issue is of a methodological nature for us, a comparison was made [7] of the calculated values and experimental data for the thermal coefficient of resistance and the so-called magnetic coefficient of giant magnetoresistance. In these cases, there was very good correspondence of these coefficients [6].…”

“…A fundamental generalization of the main results of these studies is carried out in [1]. Since 2010, intensive studies of the electrophysical, magnetic, and magnetoresistive properties of HEA, both bulk samples and coatings and thin films have begun (see, for example, [2][3][4][5][6][7][8]).…”

“…In our works [6][7][8], we described the observations of film HEA in the form of Co(20 nm)/Ni(14 nm)/ Cu(20 nm)/Fe(30 nm)/Al(15 nm)/S multilayer (S is the substrate) of the giant magnetoresistance with an amplitude of 0.30 %. We associated the realization of this effect with the spin-dependent scattering of conduction electrons on hypothetical AlNi particles [2].…”
