Özet
Mercury based copper oxide layered high temperature superconductor,which consists of superconductor–insulator–superconductor (SIS) layers, can beconsidered as a stack of nearly ideal, intrinsic Josephson junctions (IJJ). TheSIS junction, where the electrical field is confined, topologically resembles aparallel-plate capacitor. As is known, the coupling between junctions in superconductorsis capacitive. Hence, the determination of the specific capacitance (Cs) of the IJJ at thesuperconducting state has a crucial importance in order to give informationabout superconductivity mechanism. In this study, the Cs values of the investigated sample have beencalculated by means of the critical current density, Jcand plasma frequency, that have been obtained frommagnetic measurements taken at the below temperatures than the criticaltransition temperature, Tc.Moreover, Cs values at superconductingtemperature have been compared to that of the normal temperature.
