Topological superconductivity imaged by scanning SQUID microscopy

Position type: Master 2 internships and theses

Contact: Hasselbach Klaus - 0476881154 | -

We have developed a magnetic scanning microscope operating at very low temperatures (0.2 kelvin). It is a well suited tool to detect magnetic fingerprints of topological superconductivity. We use a Superconducting Quantum interference Device (SQUID) as magnetic sensor in our microscope: Flying at a height of a few nanometers above the surface of the superconductor the SQUID probe intersects magnetic flux lines acquiring thus magnetic images. During the M2 internship the student will be familiarized with the cryogenic environment and scanning probe techniques before acquiring and interpreting magnetic images of superconductors with elements of the 5f family.
