Abstract
- This research paper shows the electrical characterization of tablets type complex perovskite (Sr2FeMnO6, Ba2NdSbO6 and Sr2YSbO6 -semiconductors to room temperature) and HoBa2Cu3O7 (conductor to room temperature but superconductor to 92 K) by means of the Impedance Spectroscopy (IS) technique in solid materials. The measures were carried out in a rank of frequency of 1 mHz to 100 KHz, the experimental assembling was shown, the analysis of the impedance change based on the frequency was also shown, the elements of constant phase that appear in the transmission lines were presented, and the equivalent circuits that can be used to simulate the behavior of the electrical conductivity of these perovskites were also shown.
