Jl. Prieto et al., MAGNETIZATION PROCESSES AND OPTIMAL PERFORMANCE OF MAGNETOSTRICTIVE PIEZOELECTRIC SENSORS, Journal of applied physics, 79(9), 1996, pp. 7099-7105
We discuss the magnetization processes in sensors based on the superpo
sition of a magneto-restrictive amorphous ribbon over a piezoelectric
plate. These devices show an unusual behavior of the null condition in
the response curves, which we have related theoretically and experime
ntally to the coercive force of the magnetic sample and to changes in
the magnetic domain pattern for frequencies near the longitudinal piez
oelectric resonance frequency. (C) 1996 American Institute of Physics.
