SUPER SENSITIVE SQUID  |
Superconducting Materials
Discovery of materials with successively higher Tc’s over the last century.
(Points circled in red garnered a Nobel Prize for their
discoverers: Kamerlinbh - Onnes in 1913 and Bednorz & Muller in 1987.)
Superconducting materials:
about 30 elements are known (table A)
As, Be, Cs, Ge, Si and Te are only superconducting
oxide superconductors are a sort of ceramic(table B)
Non-superconducting materials:
normally good conductors e. g. Cu and Ag are not
magnetic materials e.g. Fe or Ni are not
transition elements are not
[1] Superconducting QUantum Interference Device
A direct current SQUID; consists of two Josephson junctions employed in parallel so that electrons
tunneling through the junctions demonstrate quantum interference, dependent upon the strength of the magnetic field
within a loop.
