Abstract
The interaction between the dislocation line and superconducting orderparameter via gauge field is discussed. In this paper the principle is a conservation law of Burgers vectors for dislocation lines. The formulationis analogous to well known electro-magnetic gauge theory. Owing to the phase of order-parameter is coupled to the gauge field with respect to dislocation line, a new type of fulxoid is quantized. Moreover this theory gives an interpretation for the magnetic flux pinning mechanism.
