We observe 2‐ and 3‐pulse echoes in CsMnF3at 2°K, by pulsing the antiferromagnetic resonance. The 2‐pulse echoes have a short decay time <0.2 &mgr;sec while the 3‐pulse echo decay is quite long, >1 sec. The 3‐pulse echo is thought to result from indirect excitation of55Mn nuclear spins which are strongly coupled to the AFR mode. The AFR echo shows double resonance effects at all four NMR modes.
