摘要：

The variations of the critical current I-c across the layers as a function of the parallel magnetic field H have been studied on small area stacked junctions fabricated from perfect single crystal Bi2Sr2CaCu2O8 whiskers. Intrinsic de Josephson effect has been clearly demonstrated on structures with in-plane size L less than 20 mu m. With L increases, a dimensional crossover to monotonic size independent behavior of I-c(H) has been observed. I-c(H) decrease in this region is proportional to root H in accordance with the Fistul-Giuliani theory.
