Abstract

The application of the small angle magnetization rotation (SAMR) method to the measurement of the saturation magnetostriction of a twisted, low-magnetostrictive wire is analyzed in the framework of the micromagnetic approximation. We show that the applied torsion introduces into the electric signal picked up from a secondary coil coaxial with the wire a fundamental harmonic contribution. Nevertheless, the measurement of saturation magnetostriction value can be performed using the same well known SAMR formula
