Flux quantization in superconducting ring
WebThis is the so-called principle of coupled flux freezing in superconducting systems, described by Equation (1). Where the potential hole is present in superconducting circuits, a coupled flux across such a circuit is constant (“frozen”). As the circuit is closed, the magnetic flux (Ψ 0) across this circuit is derived from [20,21] the ...
