2Superconductor — Supraleiter sind Materialien, deren elektrischer Widerstand beim Unterschreiten einer kritischen Temperatur Tc sprunghaft auf einen unmessbar kleinen Wert fällt. Ein Magnet schwebt über einem mit flüssigem Stickstoff gekühlten… …
3London penetration depth — In superconductivity, London penetration depth (usually denoted as lambda, or lambda L,) characterizes the typical distance to which a weak magnetic field penetrates into a superconductor.Typical values of lambda L, are between 50 and 500 nm.… …
4London moment — The London moment is a quantum mechanical phenomenon whereby a spinning superconductor generates a magnetic field whose axis lines up exactly with the spin axis.The term may also refer to the magnetic moment of any rotation of any superconductor …
5London field — Inside a superconductor, the valence electrons are free to move so free, in fact, that in the aggregate they behave like a superfluid, not subject to friction. As a consequence, during rotation of the superconductor around an axis of symmetry,… …
6London moment — noun a) A quantum mechanical phenomenon whereby a spinning superconductive metal sphere generates a magnetic field whose axis lines up exactly with the spin axis. b) The …
7Type-II superconductor — A Type II superconductor is a superconductor characterised by its gradual transition from the superconducting to the normal state within an increasing magnetic field. Typically they superconduct at higher temperatures and magnetic fields than… …
8Efecto Meissner — Saltar a navegación, búsqueda Imán levitando sobre un material superconductor. Para experimentar los efectos de la superconductividad es necesario enfriar la muestra a muy bajas temperaturas …
9Superconductivity — is a phenomenon occurring in certain materials generally at very low temperatures, characterized by exactly zero electrical resistance and the exclusion of the interior magnetic field (the Meissner effect).The electrical resistivity of a metallic …
10Superconductividad — Problemas no resueltos de la física: Superconductores de alta temperatura: ¿Por qué ciertos materiales muestran superconductividad a temperaturas mucho mayores de 50 K? …
