New composite materials consisting of polymer matrix with PZT and NdFeB microparticles were prepared and investigated in the work. It was found that magnetic properties such as saturation magnetization, coercivity, permeability, depend on mass concentration of the ferromagnetic particles in the samples. Also it was found that all samples had electrical polarization in DC external electric field. The electric properties such as coercivity, remanent polarization, the maximum polarization value, had changes in the external constant magnetic field 1.1 kOe. These changes depended on both concentrations of ferromagnetic and ferroelectric particles. This type of magnetoelectric transformation allows us to classify new materials as multiferroic materials. These new composite materials can easily be prepared of any shape, the final materials are flexible and resistant to external chemical influences. The area of application of new multiferroic materials varies from sensors to autonomous energy sources.
