With this magnetic microscope, novel quantum-structures will be investigated. These will include systems with electronic correlations, such as superconducting and mesoscopic structures, as well as nano-magnets and magnetic interfaces.  \nIn enhancing the resolution of magnetic microscopy, the combination of various techniques will be investigated, such as SQUID magnetometry with Scanning Probe Microscopy. The SQUID (superconducting quantum interference device) is the most sensitive sensor for magnetic flux currently known, and Scanning Probe Microscopy (e.g., AFM, STM) is well known for its extreme spatial resolution, down to the atomic scale. One may envision for example a SQUID-loop structured by a Focused Ion Beam around an AFM tip, prepared from a high magnetic permeability material.\nTo minimize the effects of thermal noise, and to facilitate the study of quantum-effects, the sample and the detector will be maintained at cryogenic temperatures. It is anticipated that with this research also novel techniques will be developed to enhance magnetic microscopy of samples kept at room temperature. Especially for studies on biological samples, such as neural tissue, this could be of great interest.\n\nKeywords:\nMagnetic microscopy; quantum structures; superconducting sensors.",
