Meissner Effect
The Meissner Effect is the expulsion of a magnetic field from a superconductor during its transition to the superconducting state.
Zero Electrical Resistance
Superconductors have zero electrical resistance, enabling them to conduct electricity without loss of energy.
Cooper Pairs
Cooper pairs consist of two electrons that are bound together at low temperatures in a superconductor, which are responsible for superconductivity.
Critical Temperature (Tc)
The critical temperature is the temperature below which a material exhibits superconductivity.
Type I and Type II Superconductors
Type I superconductors are characterized by a single critical magnetic field, whereas Type II superconductors have two critical fields and can enter a mixed state.
Flux Pinning
Flux pinning is a phenomenon where the magnetic flux lines are trapped and immobilized in a Type II superconductor due to defects in the material's crystal lattice.
London Penetration Depth
The London penetration depth is the distance over which a magnetic field penetrates into a superconductor and decays exponentially.
