 Snapshots of the spin configurations in the vertical section central plane through the symmetry axis of ellipsoid-shaped nanoparticle with K_C=0.5 in different fields around the coercive fields of field-cooled hysteresis loop. Hl and Hr are the fields around the coercive fields at the descending and ascending branches, respectively. (a) Hl=−0.07, (b) Hl=−0.08, (c) Hl=−0.09, (d) Hl=−0.10, (e) Hl=−0.11, (f) Hr=0.03, (g) Hr=0.05, (h) Hr=0.07, (i) Hr=0.08, (j) Hr=0.09.
