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
