This article examines the behavior of superconductivity in mesoscopic type-I superconductors based on micromagnetic measurements on two electrochemically grown mesoscopic superconductors, namely lead and tin. It first provides an overview of the basic properties of mesoscopic superconductivity and the interface between two different superconductors that are in close contact with one another. It then describes the electrochemical preparation of β-tin samples in a variety of shapes and sizes in the mesoscopic regime. It also presents the results of micromagnetic measurements, carried out using micro-Hall probes, including observations of the vortex states in mesoscopic tin and lead triangles and of proximity effects in lead/tin core–shell structures.
