Abstract
Amplification of a weak-signal spin wave by a strong pump spin wave pr opagating in an yttrium iron garnet film is observed for the first tim e. A theoretical explanation of the amplification phenomenon is sugges ted on the basis of the four-wave parametric processes. (C) 1996 Ameri can Institute of Physics.
