Relaxation dynamics of the Fe₈ molecular nanomagnet as probed by nuclear magnetic resonance.
The relaxation dynamics in molecular nanomagnets can be probed by measurements of NMR 1/T(1). By modelling magnetoelastic interactions, we theoretically investigate the behaviour of the prototype Fe(8) nanomagnet. The results of our model are in agreement with AC susceptibility and recent NMR measurements.
