| Strictly speaking, there are no examples of materials in which singlet superconductivity and ferromagnetism co-exist. |
| These chemically complex materials can, in fact, provide more information about superconductivity and magnetism than supposedly simple materials. |
| The modulation indicates a competing type of order that can also coexist with superconductivity. |
| At the end of 2000 superconductivity in metal alloys and compounds appeared to remain trapped by a glass ceiling. |
| Stripe order can coexist with superconductivity, but it tends to be associated with a drop in the superconducting transition temperature. |
| Such fields, however, do not wreck triplet superconductivity because the spins of both electrons may point in the same direction as the field. |
