Figure 7

The multiferroic structure is placed in a uniform bias DC magnetic field. Alternating magnetic fields h1cos(2πf1t) and h2cos(2πf2t) with amplitudes h1, h2 and frequencies f1, f2 are created by two electromagnetic coils K1 and K2, powered by two independent generators “AC Gen1” and “AC Gen2”.
