ABSTRACT
Coupled magnetic-mechanical-electric effects in a composite with ferromagnetic rare-earth-iron alloys (e.g., Tb[sub 1-x]Dy[sub x]Fe[sub 2]) filled in ferroelectric polymers [e.g, poly(vinylidene-fluoride-trifluoroethylene) copolymer] are studied by using the Green's function technique. Numerical results suggest a possible giant linear magnetoelectric effect in the ferroic polymer-matrix composite, which is markedly larger than that in the best-known magnetoelectric materials. In addition, the mechanically flexible composite exhibits large magnetostriction. The present results may stimulate further interest in the area of magnetoelectric materials for technological applications. © 2001 American Institute of Physics.
