Potential application of innovative magnetoelastic resonators for vibration detection

Recently, a new ferromagnetic amorphous alloy Fe62.5Co6Ni7.5Zr6CU1Nb2B15 was produced which was used as core in new magnetoelastic wave resonators. In particular, the achievement of the following innovative properties were obtained: (1) low dimension; (2) zero polarising magnetic field in standard working condition; (3) high sensitivity to local change of magnetic field; (4) low costs. A very high sensitivity to little changes of magnetic field was obtained; it can be used to detect vibrations in the range of mechanical oscillations (1-500 Hz).
