Thin coatings can be used in superconducting radio frequency cavities to minimize energy loss and reduce the inefficiency of liquid helium cooled niobium cavities.
Many superconducting ceramic materials (the high temperature superconductors) have perovskite-like structures, often with 3 or more metals including copper, and some oxygen positions left vacant.
If magnetic confinement is used, a magnet system made from superconducting magnets will be needed, as well as systems for heating and refueling the plasma.
These were replaced by electromagnets and later by superconducting magnets to achieve stronger magnetic fields for higher resolution and sensitivity studies.
Another scenario where there is an interplay between magnetic and superconducting order in the same material is superconductors with spiral or helical magnetic order.
