Abstract

In this study, Fe40Ni38Mo4B18 (2826MB) amorphous ferromagnetic ribbons were used as a magnetoelastic sensor. The variation in resonance frequency and quality (Q) factor values of samples with a 30 mm length and different widths is investigated as a function of a magnetic field. It is observed that as the sample width increases, the change in resonance frequency and the Q factor both decrease. The parameter Q x amplitude/M is defined to understand the effect of a ribbon width on the resonance curve. According to this parameter, samples with 1 and 2 mm widths are found to have a better magnetoelastic effect.
