spontaneous mode locking into state with extremely slow wave velocity for a given texture, that of the high energy AFM state (downs flipped at start). system appears to 'choose' this state as the stationary state which holds long after an intially randomized state.


regions of up and down with all in one direction, then a grouping (1/2 wavelength) will have predominantly up, and the neighboring grouping (1/2 wavelength again) will have predominantly down.  usually observed in thirds, however....


FM excitation of AFM system cannibalises randomized state as groupings of similarly aligned spins have an extremely low wave velocity and consequently their boundaries have a very high potential energy... eventually spinsystems of smaller size take over the system,

it subdivides to lower energy and cool dynamics,


large local minimum for this state, amidst all chaotic states with initially high system energy. hence it may not be a global minimum, but does attract nearby chaotic states quite readily.  


phenomena exhibited twice.
