In this study, frequency dependent electrical properties of ex situ polycrystalline MgB2 sintered at 650–850 °C were investigated. Dielectric permittivity (ε′, ε″), dielectric loss (tan δ), alternating current (AC) conductivity (σac) as a function of frequency (100 Hz–10 MHz) were measured at room t...
