In this work, frequency dependent electrical properties of the polycrystalline MgB2 synthesised at 650–850°C were investigated. Dielectric permittivity (ε’, ε”), dielectric loss (tanδ) and alternating current (AC) conductivity as a function of frequency (100Hz to 10MHz) were measured at room tempera...
