Підтримка:We acknowledge fruitful discussions with S.N. Artemenko, A.F. Volkov, P. Mueller, A. Ustinov. Yu.I.L. is grateful to the CRTBT/CNRS for hospitality. The work has been supported by Russian State Program on HTSC under the project No 93046 and by INTAS Program (Grant A 92-056).
The dependences of the critical current Ic across the layers on a parallel magnetic field H have been studied on small area stacked junctions fabricated from perfect single crystal whiskers. The intrinsic de Josephson effect has been clearly demonstrated on structures with in-plane size L less than 20μm. A dimensional crossover to monotonic size-independent behavior of Ic(H) has been observed with increase in L. The decrease of Ic(H) in this region is proportional to the square root of H in accordance with Fistul-Guliani theory.
