通过直接测量电流沿c轴沿着流动时的交流和直流约瑟夫森效应，观察到了Bi_2Sr_2CaCu_2O_8单晶中CuO双层之间的约瑟夫森耦合。结果表明，小尺寸的Bi_2Sr_2CaCu_2O_8单晶表现为一系列的约瑟夫森结，它们之间存在相位锁定。
We have observed Josephson coupling between CuO double layers in Bi2Sr2CaCu2O8 single crystals by direct measurements of ac and dc Josephson effects with current flow along the c axis. The results show that a small Bi2Sr2CaCu2O8 single crystal behaves like a series array of Josephson junctions which can exhibit mutual phase locking.
