Superconductivity (S) and ferromagnetism (F) are competing phases whose coexistence is unlikely to occur. Exceptions require a non−uniform profile both for the pairing and the magnetization, as in the case of the FFLO state ...

In the framework of the Ginzburg-Landau (G-L) theory [1], conventional superconductors are classified in type I and type II, based on the value the G-L parameter... [edited by Author]

Type II superconducting materials are technologically interesting since they are characterized by the existence of a superconducting phase even after the penetration of the magnetic field inside them. In fact, while type ...
