Abstract

We experimentally study a triangular, micrometer-sized Pb single crystal through ballistic Hall micro-probe magnetometry. This mesoscopic system allows an easy adjustment of the maximum accomodated fluxoid state by tuning the temperature. Magnetization loops of the type-I superconductor were measured at various temperatures up to T_c = 7.18 K. We observe several novel features, including mestastable fluxoid states and changes in the normal-to-superconducting transition mechanism with temperature.
