Superconductivity: The Meissner Effect, Persistent Currents and the Josephson Effects
Several phenomena associated with superconductivity are observed in three experiments carried out in a liquid helium cryostat. The transition to the superconducting state of several bulk samples of Type I and II superconductors is observed in measurements of the exclusion of magnetic field (the Meisner effect) as the temperature is gradually reduced by the flow of cold gas from boiling helium. ...

متن کاملThe penetration depth in Sr2RuO4: Evidence for orbital dependent superconductivity
– The apparent T -temperature dependence of the London penetration depth in Sr2RuO4 is discussed on the basis of a multi-gap model with horizontal line nodes. The influence of the nodes in combination with nonlocal electromagnetic response leads to low-temperature behaviors as −T 2 lnT in the London limit and as T 2 in the Pippard limit. These behaviors appear only at very low temperature. On t...
متن کاملMeissner Effect, Spin Meissner Effect and Charge Expulsion in Superconductors
The Meissner effect and the Spin Meissner effect are the spontaneous generation of charge and spin current respectively near the surface of a metal, making a transition to the superconducting state. The Meissner effect is well known but, I argue, not explained by the conventional theory; the Spin Meissner effect has yet to be detected. I propose that both effects take place in all superconducto...
