Abstract
Abstract A deep study of magnetic and magnetoelastic parameters affecting the magnetoelectric response of laminated composites working on longitudinal-transverse (L-T) mode has been carried out. Parameters such as the piezomagnetic coefficient of the magnetostrictive ribbons and the quality factor of the laminates have been analyzed in 3, 2, 1 and 0.5 cm long Fe64Co21B15/polyvinylidene fluoride (PVDF)/Fe64Co21B15 magnetoelectric composites. The obtained results show that the product of piezomagnetic coefficient and the quality factor drives the magnetoelectric response in magnetoelectric laminates, as the theoretical equations predict. Furthermore, the magnetoelectric coupling factor has been deduced from the ratio between the experimental and the expected magnetoelectric coefficients, with maximum coupling values up to 0.89 obtained for the longest laminate.
