The coherence of type I superconductor exceeds their penetration depth (ξ>λ) so it is not energically favourable for boundaries to from between their normal and superconducting phase. The superconducting element with the exception of Niobium, are all type I. When the penetration depth λ is larger than the coherence length ξ, is becomes energetically favourable for domain walls to form between the superconducting and normal regions. When such a superconductor, called type, II is in a magnetic field, the free energy can be lowered by causing domain of normal material containing trapped flux to form with low energy boundaries created between the normal core and the surrounding superconducting material.
