MAGNETOELASTIC PROPERTIES OF CoFeCrSiB AMORPHOUS RIBBONS - A POSSIBILITY OF THEIR APPLICATION

Jan Bydžovský - Mojmír Kollár - Peter Švec - Luděk Kraus - Vladimír Jančárik

   Magnetoelastic properties of amorphous \sample ribbons with x = 2, 3.3, 4, 6, 8 and 12 were investigated. Suitable composition of amorphous material and annealing conditions with respect to magnetoelastic efficiency and linearity of transfer characteristics and resistance to external magnetic fields in a wide strain interval up to 2000 microstrains were selected. A prototype of two-coil strain sensor based on these materials was tested at different magnetizing conditions. The obtained results show the possibility to use the stress-annealed amorphous ribbon with composition Co69Fe2Cr7S8B14 (ls < 0) and Co67Fe4Cr7S8B14 (ls > 0) as a potential sensor material for civil engineering applications.

Keywords: amorphous ribbons, strain sensors, civil engineering
