A SQUID (Superconducting Quantum Interference Device) is an extremely sensitive sensor for magnetic flux. Using micro-fabricated SQUID sensors, the Scanning SQUID Microscope presents a powerful scanning probe technique to locally image magnetic fields. We use scanning SQUID microscopy for various studies, such as on the occurrence of ferro-magnetism in novel thin film materials and heterostructures and for the study of fractional vortices occurring in p-phase shift structures employing the d-wave symmetry of the high-Tc superconducting state.
