Abstract :
The time delay of a magnetoelastic wave traveling in a constant field gradient is obtained for a lossless ferrimagnet without the use of the small-coupling approximation. The theory is used to calculate the delay of microwave pulses in lithium ferrite and in yttrium iron garnet single crystals. Echoes delayed by magnetoelastic wave propagation in a rectangular bar of single-crystal lithium ferrite are reported.
