Abstract

Experiments were carried out on the effect of flux pinning in type II superconductors. Several pinning mechanisms were investigated: surface pinning, bulk pinning due to grain boundaries, dislocations (caused by cold-working), and clusters of point defects (caused by neutron irradiation). The quantities determined in the experiments were the dc magnetization (or average flux density), the ac permeability components µ′ and µ″, and the heat conductivity.
