A novel frequency multiplier based on magneto electric laminate

We report a novel frequency multiplier based on the magnetoelectric( ME) effect in a simple multiferroiclaminate, made up of an amorphous FeBSiC magnetic layer bonded onto a Pb(Zr,Ti) O-3 plate wrapped with a coil. By applying an input signal with a frequency f to the coil, an output signal with 2f can be generated from the PZT plate due to the ME coupling. This ME laminate-based device can be operated in a broad frequency range and switched by a low bias magnetic field, offering potential opportunities for frequency multipliers in electrical applications.
