Fig. 4. (Color online) MOKE hysteresis loops of CoFeB films on terrace substrates with various film thickness(t) from 1 nm to 50 nm. Inset of (a) shows anisotropy enegery change depend on the thickness of CoFeB films and inset of (f) shows an AFM image of a step-terrace CoFeB film with 50 nm thickness.
