... due to cascades of spin-flips, where the flipping of a single spin alters the local fields acting on its neighbouring sites. The configuration of the spins on these sites may then no longer be locally stable, ... during the high-amplitude part of the cycle, would be effectively immobile at lower amplitudes, leading to wasted space. 6 Compaction of disordered grains...
