JOSEPHSON PHASE BLAST VALVE (VERSIONS) Russian patent published in 2017 - IPC H01L39/22 

FIELD: electricity.

SUBSTANCE: josephson phase blast valve comprises two superconducting electrodes with current leads, located on the substrate under each other, and the weak connection area between them in the form of a thin-film layered structure comprising: the intermediate layer of a superconducting material with current leads, the thickness of which ranges from 20 to 60 nm, separated from the lower superconducting electrode by an insulator layer; the normal metal layer applied to the part of the thin intermediate layer of a superconducting material, whose thickness ranges from 1 to 20 nm; the magnetic material layer applied to the surface of the thin intermediate layer of a superconducting material, remaining not covered by the normal metal layer, the thickness of which ranges from 1 to 20 nm.

EFFECT: providing the possibility of switching between the stable states of the valve without changing the magnetization in the magnetic material layer, that provides a sufficiently short time for the implementation of the write operation.
