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