Magnetoacoustic echo spectrum of a ferrite-dielectric layered structure

The spectrum of the magnetoacoustic echo arising in the structure of a ferrite film on a dielectric substrate under pulse excitation of magnetostatic waves in a tangential external magnetic field has been investigated. It is shown that the spectrum of several subsequent echo pulses (no less than 5–6) resembles that of magnetoacoustic waves in a structure under a continuous excitation regime. The fine structure of the separate echo pulse spectrum was also observed.
