采用软光刻技术制作了分辨率为100nm的微米/纳米尺度的Co点和线阵列。采用磁光克尔效应和微磁计算相结合的方法，详细研究了Co点的涡旋-单畴跃迁。证明了一个由涡旋成核引起的局部最小能量稳定的亚稳态单畴态。
Micron/nano scale Co dot and wire arrays have been fabricated by soft lithography patterning with a resolution of 100nm. Magneto-optic Kerr effect magnetometry combined with micromagnetic calculation is used to study, in detail, the vortex-single domain transition in the Co dots. A metastable single-domain state, which is stabilized by a local minimum energy induced by vortex nucleation, is demonstrated.
