Abstract

The operational dc-SQUID based on intrinsic Josephson junctions in Bi2Sr2CaCu2O8+δ high-Tc superconductor is fabricated and studied. The novel in-plane loop layout and the developed in-situ endpoint detection method allowed an accurate control of the number of junctions in the SQUID. A clear periodic modulation of the superconducting current as a function of magnetic flux through the SQUID loop is observed. This is an unambiguous evidence for the quantum interference phenomenon in Bi2Sr2CaCu2O8+δ single crystals.
