Type-I Superconductors vs. Type-II Superconductors | Superconductivity | Condensed Matter Physics

If you expose a superconducting material to a weak magnetic field, there will be no field inside the superconductor, except for a small region around the boundary, which is known as the Meissner effect. However, when you increase the strength of the magnetic field, at some point, superconductivity breaks down. The difference between type-I and type-II superconductors is, how exactly this breakdown occurs. References: [1] Tinkham, "Introduction to Superconductivity", McGraw-Hill Inc. (1996).
