Certification of new magnetic materials requires high-precision nondestructive methods. The method of measuring the magnetostriction constant of films by studying low-frequency magnetic susceptibility at elastic deformation of the films is proposed. The method allows a tenfold improvement of the accuracy of measurements of the magnetostriction constant as compared with the methods applied earlier.
The study was supported by the Russian Science Foundation, project no. 14-22-00279: Basic Research in the Field of Magnetism, Phase Transformations, Magnetoelectronics and Microsystem Technologies.
