ON THE MAGNETIC AND MAGNETOELASTIC UNIFORMITY MEASUREMENTS OF MAGNETOSTRICTIVE RIBBONS AND FIBERS

Abstract

In this paper we present results on magnetic and magnetoelastic uniformity measurements of magnetostrictive ribbons and fibers. Both magnetic and magnetoelastic measurements are based on the magnetostrictive delay line (MDL) response. Measurements were realized by using an automatic instrumentation device, with parametric control of field and frequency. The device has been calibrated with respect to standard Ni wires. Indicative results are given concerning amorphous magnetostrictive ribbons and fibers, showing a good agreement with other measuring techniques.
