METHOD FOR NON-DISTRUCTIVE CONTROL OF SUPERCONDUCTOR USING HIGH-TEMPERATURE INTERFEROMETER

摘要

A method for non-destructive control of superconductor using high-temperature interferometer comprises excitation in a film Abrikosov magnetic vortex, poles of which are located on the film surface, reading of their position by means of probe scanning. A preset structure (image) of temporary pinning center of vortexes is induced in the film by means of expose. In the film it is brought a number of vortexes that exceeds a number of pinning centers. All centers are filled with vortexes. Loose vortexes are not located on pinning centers are moved away. It is read image of real distribution of magnet vortexes in the film, compared it with preset one. According to discrepancies in images, places and characteristics of structural violation of film electromagnetic properties are localized.
