On mechanisms of single-pulse echo formation in multidomain magnetic materials

Results of comparative study of single-pulse and two-pulse echo responses a nd their secondary signals in lithium ferrite speak in favor of the effecti veness of multipulse formation mechanism of the single-pulse echo and its s econdary signals as well as the secondary signals of two-pulse echo. The ge neral source for their formation is the inequilibrity of spin system at the end of a cycle of the radiofrequency pulse train in this material. (C) 200 1 Elsevier Science B.V.
