“…As t 1 increases to 200 nm, the hysteresis loop, as shown in Fig. 1(c), changes to the characteristic loop of a film with weak perpendicular anisotropy and stripe domain structure [19]. It is noted that the saturation field increases to 150 Oe, which is about 17 times larger than the easy axis saturation field of FeNiSm films with in-plane uniaxial anisotropy, and the coercivity increases to 40 Oe.…”
