We have discussed the conditions under which a double_junction π ring magnetize spontaneously and provided the theoretical derivation. The condition is not onl y related with the parameter of induction, but also related to the ratio of the critical currents of the two junctions. Analyzing the free energy illustrates th at the spontaneous magnetization results in a stable state.
