Magnetization state images calculated using the constant magnetization method. The grey scale corresponds to white for Mx=-1.0 and black for Mx = 1.0. Images a) -- g) correspond to points on a critical field plot.

a) d/lex = 3.0, just before switching by nearly uniform rotation.
b) d/lex=17.8, just before end domain switching.
c) d/lex=17.8, just after end domain switching.
d) d/lex=17.8, just before end domain propogation.
e) d/lex=17.8, just after end domain propogation.
f) d/lex=31.6, transient state during end domain propogation.
g) d/lex=40.0, transient state during vortex propogation.

a) and b)--e) for various fields at d/lex=17.8 including b) and c) the field steps just before and after end domain switching, and d) and e) the field steps just before and after magnetization reversal via end domain propagation. Transient states f) and g) were captured during end domain propogation and vortex propogation at d/lex = 31.6 and d/lex = 40, respectively.
