Future Strain Properties of Multilayer Film Materials

The results of analysis of literature and own data on the phase composition, electrophysical and magnetoresistive properties of granular film alloys based on Fe and Ag or Au are present. Analyzed the question about system designations of film structures, which adopted in the literature and does not meet their physical nature in its original state and after annealing. A new system of signs ordered and disordered solid solutions without and with the presence elements of granular state; quasigranular alloys, in which the role played granules of ferromagnetic island films; intermetallic and others was proposed. It is established that the electrophysical properties (temperature coefficient of resistance-TCR and strain coefficient-SC) defined conductive matrix as s.s., and in nanoscale granules realized the ballistic conductivity mechanism that does not affect the value of TCR and SC. In granular film alloys s.s. Au (Fe) + granules at the plastic deformation observed abnormal increase in comparison with the elastic deformation value SC (10 times) at a concentration cFe  55-75 аt. %.

“…At the V and VI strain cycles there is also a kind of strain to quasiplastic because there was a relaxation of plastic strain of the II type. Described feature of two-stage at the strain effect never observed in the case of single-layer or multilayer films (see., for example, review [18,19]), with their plastic strain.…”

The results of research the phase composition and electrophysical (resistivity, thermal coefficient of resistance, strain coefficient) and magnetoresistive properties (anisotropic magnetoresistance) of thin films (to 40 nm) high entropy alloys (HEA) based on Al, Cu, Ni, Cr, Fe, Co and Ti. It is established that after forming the layered samples by electron condensation on diffraction pattern fixed lines from the two phases of the fcc lattice and actually tracks the bcc phase. After homogenization by annealing the samples is one of the fcc phase s.s. HEA and traces bcc phase (likely s.s. (-Fe, Cr)), that samples are single phase. The study electrical properties allowed watching the first double-stage plastic deformation of a large value of the coefficient gauge (300 units), watch probably, is typical for НЕА. The character dependences MR from induction indicates to realization of anisotropic magnetoresistance.
