Çavdar, H. Koralay, Ş. Altındal] Glass ceramic superconductors were prepared by the melt-quenching method. The frequency and temperature dependence of dielectric constant (ε′), dielectric loss (ε″) and loss tangent (tan δ) of these superconductors were investigated in the frequency range of 10kHz-10MHz and temperature range of 80-300K using the capacitance-voltage (C-V) and conductance-voltage (G/w-V) measurements. Effect of vanadium on bulk properties, dc electrical resistivity (ρ) and ac electrical conductivity (σ ac) of these superconductors were also investigated. The experimental results showed that ε′,ε″ and σ ac were strongly temperature and frequency dependent. Negative capacitance (NC) phenomenon has been observed and it is believed that the negative capacitance effect is due to polarization effect. The results can be concluded to imply that the interfacial polarization can occur more easily at low frequencies consequently contributing to the deviation of the dielectric properties and ac electrical conductivity of Bi2Sr2Ca1Cu2Oδ and Bi1.9V0.1Sr2Ca1Cu2Oδ superconductors.
