Examples of superconductivity in the following topics:

  • Temperature and Superconductivity

    • Superconductivity is a phenomenon of zero electrical resistance and expulsion of magnetic fields in certain materials below a critical temp.
    • In superconducting materials, the characteristics of superconductivity appear when the temperature T is lowered below a critical temperature Tc.
    • For example, the electronic heat capacity is proportional to the temperature in the normal (non-superconducting) regime.
    • The Meissner effect is a defining characteristic of superconductivity.
    • Behavior of heat capacity (cv, blue) and resistivity (ρ, green) at the superconducting phase transition.
  • Primary Market Research

    • An example of primary research in the physical sciences: Can the transition temperature of high-temperature superconductors be increased by varying the composition of the superconducting material.
    • An example of primary research in the physical sciences: Can the transition temperature of high-temperature superconductors be increased by varying the composition of the superconducting material.
  • Absolute Zero

    • Scientists have brought systems to temperatures very close to absolute zero, at which point matter exhibits quantum effects such as superconductivity and superfluidity.
  • X-Ray Spectra: Origins, Diffraction by Crystals, and Importance

    • For example, current research in high-temperature superconductors involves complex materials whose lattice arrangements are crucial to obtaining a superconducting material.
  • The Uncertainty Principle

    • These include, for example, tests of number-phase uncertainty relations in superconducting or quantum optics systems.
  • Other Forms of Energy

    • An example of something that stores magnetic energy is a superconducting magnet used in an MRI.
  • Magnitude of the Magnetic Force

    • The strongest permanent magnets have fields near 2 T; superconducting electromagnets may attain 10 T or more.
  • The Pauli Exclusion Principle

    • Bosons include the photon, the Cooper pairs (responsible for superconductivity), and the W and Z bosons.
  • Molecular Crystals

    • However, inserting (intercalating) alkali metal atoms between the fullerene molecules provides extra electrons, which can be easily ionized from the metal atoms and make the material conductive, and even superconductive.
