Nano scale hysteresis loops of fatigued FeCaps

2 Nano scale hysteresis loops of fatigued FeCaps 

The following features of the central picture should be emphasized  

the fatigued state is highly inhomogeneous (phase and amplitude) 

at higher electric fields almost all the points show a phase change 

the degree of fatigue at the observed scale (30x30 nm) appears to vary smoothly
