In physics, the Josephson effect is a phenomenon that occurs when two superconductors are placed in proximity, with some barrier or restriction between them.
Brian David Josephson FRS (born 4 January 1940) is a British theoretical physicist and professor emeritus of physics at the University of Cambridge. [3] Best known for his pioneering work on superconductivity and quantum tunnelling , he was awarded the Nobel Prize in Physics in 1973 for his prediction of the Josephson effect , made in 1962 when ...
The principle of the dc Volt: Put 5000 Josephson junctions in series, and apply a fixed frequency, which can be done very accurately, and measure the interval of the resulting dc voltages that occur at precise voltage intervals.
The Josephson effect is central to the operation of the superconducting quantum interference device (SQUID), which is a very sensitive detector of magnetic fields. It is used to measure tiny variations in the magnetic field of the Earth and also of the human body.
