Sa. Nikitov, ACOUSTIC-WAVE PULSE GENERATION UNDER THE NONLINEAR MAGNETOELASTIC INTERACTION OF 2 SPIN-WAVE PULSES, Journal of magnetism and magnetic materials, 164(1-2), 1996, pp. 172-174
Acoustic wave generation under the interaction of two spin wave pulses
propagating with different velocities in a ferromagnetic film has bee
n predicted. The width of the acoustic wave pulse is thousands of time
s greater than the width of the spin wave pulses. The peak amplitude o
f the acoustic wave pulse is proportional to the correlation function
of the amplitudes of the spin wave pulses.
