观察控制域结构的锯齿形图案的钴线证明。通过改变磁场的方向，可以获得不同的磁畴结构，这为设计所需的磁结构提供了潜在的可能性。利用这种精细的技术，我们进一步揭示了不同畴结构引起的磁电阻问题。结果表明，Z字形线转角处的自旋组态对电阻有负贡献，在100 K附近出现反常的最大值.
Observations of controlled domain structures in zigzag patterned cobalt wires are demonstrated. Distinct domain structures are accessible by changing the orientation of magnetic field using the zigzag geometry, which provides a prospective potential to design the desired magnetic structures. Utilizing the subtle technique, we further throw light on the issue of magnetoresistance induced by the different domain structures. It is found that a negative contribution to the resistance is due to the spin configuration around the corner of the zigzag wires and shows an anomalous maximum around 100 K.
