The Phenomenon of Superconductivity and Type II Superconductors, the magnetic field is expelled out of the body of the superconductor. Field penetrates the material only a small distance, called London’s penetration depth, . which is of the order of 30–60 nm in metal superconductors. These materials also exhibit flux quantization insofar as the field entering a

A Review of Theories of Superconductivity,onductor with a vector potential and using Maxwell equations. Theory explained well the vanishing of resistivity and the occurrence of Meissner effect in metallic superconductors. An expression for Londons’ penetration depth . was given which was confirmed experimentally. Another phenomenological th

Conventional Practical Superconductors,state. These instabilities lead to premature quench in superconducting magnets. To circumvent the problem, practical superconductors are produced in the form of fine filaments in high conductivity copper matrix. Most popular superconductor Nb-Ti had been produced this way by co-processing it with Cu

Practical Cuprate Superconductors,d Bi-2212. The best superconductor the so-called 2G REBCO-‘coated conductor’ is produced by depositing highly oriented thin film of (GdY)BCO on biaxially textured Hastelloy substrates buffered with a number of oxide layers. The tape conductor is suitably laminated with Ag-alloy and then a high condu

Iron-Based Practical Superconductors,ron, which has large magnetic moment, was traditionally considered as an opponent of superconductivity because of the contradiction between the static electron spin ordering in Fe and dynamic formation of electron pairs of opposite spins in superconductors. The discovery opened the floodgate to the

Building Laboratory Superconducting Magnets and Present Status of High-Field Magnets,or physical property measurements. Broad parameters discussed are the design dimensions, homogeneity, current lead optimization, quench protection and persistent current switches. Multifilamentary Cu.Nb-Ti conductor is the universal choice for building (multi-section) magnets producing field up to 8
