Abstract:
We report measurements of the ΔG effect and magnetomechanical damping in as-quenched and annealed amorphous wires of Co72.5Si12.5B15 having a saturation magnetostriction λs of about -3 × 10-6. Samples were measured in the as-quenched state, and after annealing at 450°C for times between 30 s and 1000 min. ΔG of up to 10% and magnetomechanical damping up to 0.004 have been found.
