PhD project: Low-temperature Magneto-Kerr Microscopy

Project description

This project will extend the operation of a magneto-Kerr microscope to work at progressively lower temperatures, ulimately down to 0.1 K. The microscope will be used to image a variety of magnetic structures starting with domain structures in magnetostrictive materials patterned in-situ with ultrasonic waves (at room temperature). Such materials may have applications in magnetic storage and energy recovery. At lower temperature the microscope will be used to image domain structures in ferromagnetic superconductors (URhGe and UCoGe). These 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).
