| Annotation | 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. |
