Reply to the 'Comment on Ultralow magnetostrictive flexible ferromagnetic nanowires' by D. Faurie, N. Challab, M. Haboussi, and F. Zighem, Nanoscale, 2022, 14, DOI: 10.1039/D1NR01773J COMMENT

In the comment to our paper, D. Faurie et al. have carried out simulations on Co-nanowires subjected to tensile stress perpendicular to the length of the nanowires. According to their simulation, the low effective magnetostriction constant of the Co nanowires results from a very low transfer of stress. They suggest that a higher transfer of stress would be obtained if the wires are bent along the length of the nanowires. Here we compare the result of magneto-optical experiments conducted by bending the nanowires both along and perpendicular to their long axis. The obtained effective magnetostriction of the Co-nanowires is, within the experimental resolution, independent of the bending direction.

Automated summary

The effective magnetostriction of Co-nanowires is found to be independent of the bending direction, as shown by comparing magneto-optical experiments conducted with nanowires bent along and perpendicular to their long axis.
