Investigation of Morphology, Optical and Electronic Ac Conduction of the Olivine Manganite Compound: NaMnPO4

“…The presence of multivalent ions in this sample and associated hopping events may be the cause of the dielectric behavior seen in the NaMnPO 4 compound. Several findings suggested that adding Mn to the mix resulted in a drop in the dielectric constant [72] . Although locking through charge‐balanced couplings between distinct ions found at various valence levels may reduce polarization, electron jumping between similar ions living in different valence states can boost polarization.…”

An investigation of structural, thermal, and electrical conductivity properties for understanding transport mechanisms of CuWO4 and α-CuMoO4 compounds

“…Electrical conductivity is a thermally activated process that relies on the ordered movement of lightly bound charged particles while being affected by a continuous electric field. The following equation can be used to determine the electrical conductivity of the grain ( σ g ) at each temperature, derived from the resistance values obtained from the equivalent circuit: 28 where R g is the resistance of grain determined by the adjustment, S is the area of the electrode that is deposited on the pellet, and e is the thickness of the sample.…”
