Definition

quotient of penetration depth of a magnetic field into a superconductor and the coherence length of thermodynamic fluctuations within a superconducting phase in a material at zero thermodynamic temperature, expressed by

$κ = λ_{L} / (ξ \sqrt{2})$ ; where

$λ_{L}$ :: is London penetration depth (ISO 80000-12: Condensed matter physics), and +

$ξ$ :: is coherence length (ISO 80000-12: Condensed matter physics)

quotient de la profondeur de pénétration d'un champ magnétique dans un supraconducteur par la longueur de cohérence des fluctuations thermodynamiques dans une phase supraconductrice d'un matériau à une température thermodynamique nulle, exprimé par:

$κ = λ_{L} / (ξ \sqrt{2})$ ; où

$λ_{L}$ :: est la profondeur de pénétration de London (ISO 80000-12: Condensed matter physics); et

$ξ$ :: est la longueur de cohérence (ISO 80000-12: Condensed matter physics)
