Search for nonlinear THz transmission in a multiferroic Z-hexaferrite
Original language description
Magnetoelectric multiferroics are promising materials due to their potential as electricfield-controlled magnetic memories; moreover, writing could be done in principle by fast THz electric field via an electromagnon excitation. Since any writing of information is associated with some nonlinearity, we attempted observing nonlinear transmission of the electromagnon in Z-hexaferrite (Ba0.2Sr0.8)3Co2Fe24O41 ceramics. We observed a change of electromagnon absorption and frequency with intensity of THz radiation, but the discovered effect is caused by heating of the sample by THz radiation and not by non-linear electromagnon absorption. We then determined lower bound of the linear electromagnon-induced polarization as 11 –113 μC/m2. We propose some improvements of the current experiment as well as propose another experiment which can possibly determine linearity limit.
