Cumulative 57fe Nmr Stimulated Echoes in Lithium Ferrite

Abstract
The results of the cumulative NMR stimulated echo phenomena study in lithium ferrite are presented. These echo signals are generated by the joint action of a train of weak writing radio-frequency pulses and exhibit the growth of intensity at increasing the number of exciting radio-frequency pulses rather than decay. Similar effect was earlier observed for the case of cumulative stimulated photon echo. Keywords- NMR, lithium ferrite, stimulated echo, cumulative NMR echo, cumulative photon echo.
