Abstract

Laws of reversible change of a critical current and discrete current states of the structure in the form of superconducting quantum interferometer, shunted by superconducting inductance are established, at passing through the structure alternating transport current and at simultaneous influence with a transport current of an external alternating magnetic field. The new type of discrete stationary states of the structure is found out at transition of an interferometer in a resistive state caused by joint action of direct and alternating transport currents.

Key words: quantum interferometer, shunting inductance, transport current, magnetic field, discrete states.
