Parametric interaction of a dipolar spin wave pulse with electromagnetic field of a localized nonstationary (pulsed) pumping is studied experimentally and theoretically in yttrium-iron garnet (YIG) films. This interaction leads to the effective amplification of the incident BVMSW pulse, and also to the formation of a phase-conjugated and amplified pulse propagating in the reverse direction. Numerical calculation of amplification and conjugation coefficients are in good quantitative agreement with experiment.
