Cryotron

The cryotron is a switch that operates using superconductivity. The cryotron works on the principle that magnetic fields destroy superconductivity. This simple device consists of two superconducting wires ( e.g. tantalum and niobium) with different critical temperature (Tc). The cryotron was invented by Dudley Allen Buck of the Massachusetts Insti...

cryotron

cryotron (krī'ōtron") , magnetically controlled electronic switching device that operates at extremely low temperatures; it is designed to supplant, in part, the transistor in special electronic equipment (e.g., the computer). One type of cryotron consists of a straight wire (the...

cryotron

cryotron A cryogenic device that uses the principle that a varying magnetic field can cause the resistance of a superconducting element to change rapidly between its high normal and low superconductive values: used as a switch and as a computer-memory element.
