This chapter is devoted to the strain properties of multilayer thin-film materials based on metals. Although this problem is the subject of study researchers, many questions remain poorly understood, which include the development of a theoretical model of the tensoresistive effect for multilayer films and a comparative analysis of its features in the range of elastic and plastic strain and temperature dependence of strain coefficient. This work also focuses on the question about increase of strain coefficient through the surface, grain boundary and interface scattering of electrons. The purpose of this work is analytical analysis of the known theoretical models of tensoresistive effect: linearized and three-dimensional Tellier–Tosser–Pichard models for one layer and semiphenomenological model for multilayer by authors of this work, which takes into account the dependence of the electron transport parameters (mean free path, specularity parameter and transmission coefficient at the boundary and interface). The purpose of this work was to compare the theoretical models and experimental results obtained in the field of elastic deformation and analysis of the temperature dependence of strain coefficient and the insufficiently explored question of magneto-deformation effect. The presented results allow us to more accurately describe the physical processes in the multilayer films under strain, especially to understand the processes in the elastic and plastic strain and the conclusion on the application of multilayer films as sensitive elements of sensors strain, magnetic field and pressure.

The tensoresistive effect in single-layer Cr, Fe, Mo, Ni, and Pd films and double-layer Fe/Cr, Cu/Cr, Ni/Cr, and Pd/Fe films is studied in the range of elastic and plastic strain. The influence of the surface and grain-boundary scatterings of electrons on strain sensitivity Sρ of the single-layer films is analyzed. Sensitivities Sρ of the single- and double-layer films to elastic and plastic strains are compared. It is found that the volume and grain-boundary scatterings of electrons are main contributors to Sρ in the Fe/Cr film system. Grain-boundary scattering is equally effective under elastic and plastic strain, as judged by a high coefficient of electron grain-boundary scattering (R ≌ 0.36–0.41).

A new method for the formation of functional elements of spin-valve structures is proposed, which is based on the sequential condensation of nanodimensional Co, Cu, Au, and Cr layers with certain heat treatments in the course of condensation. The magnetooptical and magnetoresistive properties of structures obtained using the proposed method have been studied. Relationships between these properties and the structure and phase state of the spin-valve sandwiches and their components are established.

The results of research of phase composition and thermoresistive properties of nanodimentional film materials based on Pd or Au and Fe or W, indicating their high thermal stability in the temperature range 300-850 K. The conclusion about the possibility of using such materials as diffusion barriers for multilayer metallization systems in elements of integrated electronics (films based on Pd and W) and sensitive elements of thermistor and temperature sensors (film based on Pd or Au and Fe).
