我们开发了高 TC SQUID 探针显微镜与扫描隧道显微镜相结合，用于在室温下研究空气中的样品。使用高磁导率探针作为磁通量导向器以提高空间分辨率。通过微电解抛光制备了尖端半径小于100 nm的探针。该探针还用作扫描隧道显微镜尖端。样品表面的形貌可以通过具有高空间分辨率的扫描隧道显微镜进行测量。在保持样品表面到探针尖端的距离恒定的情况下，可以观察SQUID探针显微镜图像。我们观察了Ni精细图案的形貌图像和磁图像以及磁记录硬盘。
We have developed a high TC SQUID probe microscope combined with a scanning tunneling microscope for investigation of samples at room temperature in air. A high permeability probe needle was used as a magnetic flux guide to improve the spatial resolution. The probe with tip radius of less than 100 nm was prepared by microelectropolishing. The probe was also used as a scanning tunneling microscope tip. Topography of the sample surface could be measured by the scanning tunneling microscope with high spatial resolution. The SQUID probe microscope image could be observed while keeping the distance from the sample surface to the probe tip constant. We observed a topographic image and a magnetic image of Ni fine pattern and also a magnetically recorded hard disk.
