Abstract : Two and 3-pulse echoes were observed in CsMnF3 at 2K, by pulsing the antiferromagnetic resonance. The 2-pulse echoes have a short decay time < 0.2 microsec while the 3-pulse echo decay is quite long, > 1 sec. The 3-pulse echo is thought to result from indirect excitation of 55Mn nuclear spins which are stongly coupled to the AFR mode. The AFR echo shows double resonance effects at all four NMR modes.
