摘要
我们提出了一种基于场导向氩离子刻蚀铁针尖的配方，该配方可制备出适用于稳定自旋极化扫描隧穿谱的探针。通过对Cu(111)上Co岛磁化强度的谱学映射测量，说明了这一点。

备注
The results are described only in a qualitative manner and no quantification is provided to support the drawn conclusions. The results are based on a very limited number of STM tips, which makes the significance of the claims questionable
