Superconductors Type II |
|
| Superconductors made from alloys
are called Type II superconductors. Besides being
mechanically harder than Type I superconductors, they
exhibit much higher critical magnetic fields. Type II
superconductors such as niobium-titanium (NbTi) are used
in the construction of high field superconducting magnets.
Type-II superconductors usually exist in a mixed state of normal and superconducting regions. This is sometimes called a vortex state, because vortices of superconducting currents surround filaments or cores of normal material. |
