Czechoslovak Journal of Physics Aims and scope

Abstract

Appropriate amorphous material composition and annealing conditions providing the magneto-elastic efficiency and linearity of the transfer characteristics in a wide interval of strain were found. A prototype of the two-coil strain sensor based on these materials was tested at different magnetizing conditions. The obtained results show a possibility to use the stress annealed·amorphous ribbons of the composition Co69Fe2Cr7Si8B14 (λs<0) and Co67Fe4Si8B14 (λs>0) for sensors in civil engineering applications.
