The proposed device is composed of three superconducting rings interconnected via a core with a high magnetic permeability μ r ≫ 1 in a transformer-like arrangement, as depicted in Fig. 1.The input ring (leftmost in Fig. 1) is used to bias the central/bit ring … WebJul 5, 1999 · 74.25.-q. London [1] first recognized that the magnetic flux ought to be quantized in superconductors. He suggested that the magnetic flux trapped in the bore hall of a cylindrical superconductor would be integer multiples of a fundamental quantum of flux Φ0 = hc / e (=4×10 −7 G cm 2 ). The experiments on the flux quantization carried ...
