Abstract
Disclosed is the structure of a persistent current switch and a control method for the same. In the switch structure, a portion of a superconducting wire to be used as a switch is formed with slits such that the flow of current is controlled by the switch, to facilitate a transition between the superconducting state and the normal state of the superconducting wire. The structure of the persistent current switch includes a first slit longitudinally extending from a first point on one end of a superconducting wire to a second point and from a third point to a fourth point, the second, third, and fourth points being arranged sequentially in a longitudinal line, and second and third slits provided at opposite sides of a region between the second point and the third point where no first slit exists.
