The dissipative component of electron transport through the doubly connectedSNS Andreev interferometer indium (S)-aluminium (N)-indium (S) has beenstudied. Within helium temperature range, the conductance of the individualsections of the interferometer exhibits phase-sensitive oscillations ofquantum-interference nature. In the non-domain (normal) state of indiumnarrowing adjacent to NS interface, the nonresonance oscillations have beenobserved, with the period inversely proportional to the area of theinterferometer orifice. In the domain intermediate state of the narrowing, themagneto-temperature resistive oscillations appeared, with the period determinedby the coherence length in the magnetic field equal to the critical one. Theoscillating component of resonance form has been observed in the conductance ofthe macroscopic N-aluminium part of the system. The phase of the oscillationsappears to be shifted by $\pi$ compared to that of nonresonance oscillations.We offer an explanation in terms of the contribution into Josephson currentfrom the coherent quasiparticles with energies of order of the Thouless energy.The behavior of dissipative transport with temperature has been studied in aclean normal metal in the vicinity of a single point NS contact.Comment: 9 pages, 7 figures, to be published in Low Temp.
