Abstract

All magnetostrictive types of soft magnetic materials show some weak sensitivity to processes of bending. However, as demonstrated here, a prerequisite for high sensitivity values is that the profile of material exhibits asymmetry with respect to physical characteristics. Specific technological processes yield ultra high sensitivity, a curvature of 1/m causing permeability changes of more than 50%.
