superconductivity

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.

• 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.

• 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.
