CONT

Of the techniques used to produce such temperatures on the ground, adiabatic demagnetisation refrigeration (ADR) is the most promising for adaptation to use in space. ADRs utilise the magnetocaloric effect, the reduction in temperature observed when an external magnetic field is applied isothermally to a paramagnetic material, and then removed adiabatically.

OBS

For superconducting tunnel junctions.

PHR

10 mK adiabatic demagnetisation refrigeration.

OBS

En 1956, madame Wu et messieurs Ambler, Hayward, Hoppes et Hudson [...] montrent que les électrons provenant de la désintégration béta de noyaux de Cobalt 60, refroidis par démagnétisation adiabatique et dont le spin a été orienté dans un champ magnétique, ne sont pas répartis symétriquement au-dessus et au-dessous du plan perpendiculaire aux spins des noyaux de cobalt.

PHR

Refroidissement à 10 mK par démagnétisation adiabatique.
