Popis: This study examines the effect of the loss-damping $$\eta$$ coefficient and the stress magnetostrictive coefficient $$\delta$$ on the magnetoelectric (ME) phenomenon in bi-layer composites consisting of a polyurethane layer loaded with magnetic $${\text{Fe}}_{3} {\text{O}}_{4}$$ nanoparticles glued to piezoelectric ceramic. A model based on a driven damped oscillation system has been developed to evaluate the influence of the η and δ coefficients on ME current response $$(i_{{{\text{ME}}}} )$$ versus bias magnetic induction $$(B_{{{\text{dc}}}} )$$ . A good agreement was obtained between the simulated and experimental results; additionally, the magnitude of ME current increased with an increase in $$B_{{{\text{dc}}}}$$ , and also increased with an increase in δ and a decrease in $$\eta$$ . However, the phase shift $$\phi$$ between $$i_{{{\text{ME}}}}$$ and alternative magnetic induction $$B_{{{\text{ac}}}}$$ presents a phase-switching phenomenon—namely, the point at which the curve $$\phi (B_{{{\text{dc}}}} )$$ switches by $$\pi$$ displaced from the center $$(B_{{{\text{dc}}}} = 0 T)$$ —as well as the curve displaced toward lower when $$\eta$$ increased or $$\delta$$ decreased. Consequently, the ME current and the phase-switching phenomenon are mainly influenced by the magnetostrictive and the loss-damping coefficients.
