Echo of magnetostatic modes in YIG films
Serga A. A., Tychinskii A. V.
Experimental results are reported on the observation of an echo in tangentially magnetized epitaxial films of yttrium iron garnet (YIG) during excitation of magnetostatic waves with fixed propagation directions with respect to the magnetizing field. The results support the suggestion that the echo process in YIG films is associated with slow surface magnetostatic waves which are propagating near critical angles.
