The bi- and tri- layered magnetoelectric composites were fabricated from magnetic Fe49Rh51 and piezoelectric PbZr0.53Ti0.47O3 materials. It was shown the electric field-induced stresses reduce the magnetization around magnetic phase transition temperature of Fe49Rh51: by 5.4% for tri-layer PZT/FeRh/PZT composite and by 3.6% for bi-layer FeRh/PZT composite. The magnetoelectric properties were studied at 320 K, the magnetization rate was estimated for the magnetic field of 0.5 T. The heterogeneous distributions of stresses and magnetization in volume of magnetic layer under applied magnetic and electric fields were demonstrated using COMSOL Multiphysics software. The obtained results demonstrate the tri-layered composite is more effective for tuning the magnetization
