Essay

The operation of a spin-wave parametric amplifier in over-threshold non-stationary modes is analyzed. Non-adiabatic interaction as well as the phenomena of wave front reversal and inversion of the time profile of a spin wave signal were realized. Amplification of one- and two-dimensional envelope solitons were investigated. New types of nonlinear eigen-excitations of a resonance ring have been discovered. A new method of relaxation reversal of oscillatory motion based on a frequency-selective amplification of secondary excitations is proposed.
