Supplementary Material - Micromagnetic simulation of the magnetization-controlled critical current in a S-(S/F)-S superconducting switch

Detailed discussion of the grain size in the simulation and the experimental sample, arguments for our choice of critical current density Jc(B) model, the effect of different choices of coherence length xi in the model and a discussion on the 2nm cell size choice. Also statistical variations in simulated Ic(B_train) curves are presented.

针对模拟与实验样品中的晶粒尺寸（grain size）展开详尽讨论，论证我们选取临界电流密度（critical current density）Jc(B)模型的依据，分析模型中选取不同相干长度（coherence length）ξ所带来的影响，并对2nm单元尺寸（cell size）的选取方案展开探讨；同时给出了模拟得到的Ic(B_train)曲线的统计涨落（statistical variations）特性。
