Параметрическое усиление магнитоакустических колебаний в структуре ферромагнетик-пьезоэлектрик
Keyword(s):
Parametric amplification of magnetoacoustic oscillations was observed in a disk resonator containing a ferromagnetic layer of FeBSiC and a piezoelectric layer of lead zirconate-titanate. Oscillations with a frequency of 3.08 kHz were excited and recorded using two coils with orthogonal axes. Pumping was performed by an electric field with a double frequency applied to the piezoelectric layer. The amplification of vibrations arises due to a change in the rigidity of the structure under influence of an electric field. It is shown that the gain can be changed using a permanent bias magnetic field applied to the structure.
