Abstract :
A new, inexpensive and fast method for determining the magnetoelastic uniformity of amorphous magnetostrictive ribbons and wires is proposed. Such a method is based on the response of a magnetostrictive delay line (MDL) when a pulsed magnetic field acoustically excites the whole line. Results are given showing an improvement of the unformity after stress current annealing
