Vortex pinning in MgB2 superconductors

Chapter


Abstract


  • Superconductivity was one of the most studied topics in the

    last 20 years, thanks to the discovery of high-temperature

    superconductors (HTSs). Exotic features of superconductivity

    are direct consequence of quantum-mechanical phenomena.

    Quantum-mechanical phenomena are applicable to nanoscopic

    world. However, superconductivity is' an exception to

    this because it is a collective state of quantum-mechanical

    entities (i.e., charge carriers, such as electrons) that extends

    through whole of the superconductor on a macroscopic scale.

    Thanks to this, quantum-mechanical phenomena associated

    with superconductivity can be observed and used in our

    macroscopic world. Most common examples of this are transport

    of electrical current with no resistance and levitation.

    Such phenomena can be compared to the motion of electrons

    around atomic nuclei without loss of energy through radiation,

    which can only be described by quantum mechanics.

    Superconductors offer experience of such phenomena in our

    everyday world, with a possibility of practical applications of

    these phenomena in our macroscopic world.
