Amplification of magnetoelectric conversion in ferromagnet-magnetoelectric-ferromagnet structures

The linear magnetoelectric effect in hybrid structures ferromagnet - magnetoelectric - ferromagnet at low frequencies is experimentally investigated. It is shown that the use of a ferromagnetic as a component of the structure leads to an increase in the magnetoelectric conversion by a factor of twenty, while the bias field decreases by a factor of seventy. It was found that these effects are due to an increase in the magnetic field acting on the magnetoelectric.
