The results of investigation strain properties (integral (γl)int and differential (γl)dif  strain coefficients) of thin film nanostructures based on permalloy Ni80Fe20 (Ру) silver (Ag), prepared by method of co-evaporation from independent sources, and results for components of the systems are presented. The main peculiarities of Py and Ag strain properties in the range of thicknesses d = 10-60 nm are determinate. It has been shown that the maximum at the сAg = 30-36 at.% is observed at the concentration dependences of (γl)int. The presence of a maximum is due to the structural changes in the film systems.
