Abstract
Abstract The most prominent macroscopic quantum mechanical effects in superconductivity are beside the zero electrical resistance the Meissner effect (magnetic field expulsion) and magnetic flux trapping (pinning) in materials in their superconducting state. Their i vestigations are still subject of many publications because of the lack of consistent models or a theory which describes flux domains or flux trapping in e.g. type-I superconductors. The spin of the neutron interacts with magnetic fields which can be visualized by radiography (and tomography) using polarized neutrons. It could be shown that both the Meissner effect and flux trapping in high purity lead samples (type-I super-conductor) occur different for the crystalline and polycrystalline samples, respectively. The trapped flux of an uni- form external magnetic field applied to the lead samples is for T
