PhD project: Low-temperature Magneto-Kerr Microscopy

Project description

We are building a magneto-Kerr microscope built to work at progressively lower temperatures, ulimately down to 0.1 K. The microscope will be used to image domain structures in ferromagnetic superconductors (URhGe and UCoGe). The images will be used to position contacts to make transport measurements across single domain walls and to test for the presence of Josephson currents (Shapiro steps etc). The microscope will also be used to look for surface currents around domain edges that are signatures of topologically protected states associated with some non-conventional order parameters (with applications in quantum computing) to image vortice densities to look for new behaviours predicted at domain walls.
