19 Sep 1996 | Journal: | Czech. J. of Phys. 46, Suppl. S6, 3107 (1996) | Subject: | cond-mat | Affiliation: | CRTBT-CNRS, Grenoble, France, LMM-CNRS, Bagneux, France, IRE-RAS, Moscow, Russia | Abstract: | We review transport measurements in a normal metal (N) in contact with one or two superconducting (S) islands. From the experiment, we distinguish the Josephson coupling, the mesoscopic fluctuations and the proximity effect. In a loop-shaped N conductor, we observe large h/2e-periodic magnetoresistance oscillations that decay with temperature T with a 1/T power-law. This behaviour is the signature of the long-range coherence of the low-energy electron pairs induced by the Andreev reflection at the S interface. At temperature and voltage below the Thouless energy $hbar D / L^2$, we observe the re-entrance of the metallic resistance. Experimental results agree with the linearized quasiclassical theory. | Source: | arXiv, cond-mat/9609182 | Services: | Forum | Review | PDF | Favorites |
