Abstract

The results of the cumulative NMR stimulated echo phenomenon study in lithium ferrite are presented. This echo is generated by the joint action of a train of weak writing radio-frequency pulse pairs and final reading single radio-frequency pulse which exhibits the growth of intensity at increasing the number of exciting radio-frequency pulse pairs.

Similar effect was earlier observed for the case of cumulative stimulated photon echo. The obtained results could be understood in the frames of a simple theoretical model of cumulative NMR stimulated echo formation.
