我们报告超导铁磁体层状结构的实验研究。观察到临界超导电流随铁磁体厚度变化的强烈振荡。使用已知的微观参数的Ni，我们发现合理的协议之间的振荡周期和衰减的测量临界电流，和理论计算。
We report on experimental studies of superconductor-ferromagnet layered structures. Strong oscillations of the critical supercurrent were observed with the thickness variation of the ferromagnet. Using known microscopic parameters of Ni, we found reasonable agreement between the period of oscillations and the decay of the measured critical current, and theoretical calculations.
