Publication date: Available online 14 August 2019Source: Physics Letters AAuthor(s): Bibhuti B. Sahu, S.K. Patri, Banarji BeheraAbstractBa2Zn2Fe12O22 was synthesized by solid state reaction technique. The strongly temperature and frequency dependent electrical properties and complex impedance spectroscopy were analysed. Complex modulus formalism shows the existence of high resistance and small capacitance of the materials for the short range relaxation. The presence of non-Debye type relaxation is revealed from Nyquist plots and enabled to separate the contribution from bulk and grain boundary effect in the material. Further, the ac electrical conductivity of the material was well agreed with the Jonscher's universal power law.
