The lithium cobalt ferrite with different concentration, Li0.75Co(5+3x/8)Fe2-yO4 (x = 0, 1, 2, 3, 4) (y 0.25, 0.5, 0.75, 1) were synthesized by sol-gel process. structural, morphological, magnetic and electrical properties investigated XRD, FESEM-EDS mapping, FTIR, VSM impedance techniques. addition of lithium, a reactive soft alkali metal, greatly improves the electrochemical conduction processes when it is blended ferrite. change from bulk to nanomaterials results in significant alterations its physical, characteristics, substituting alters pure into magnetically active substance. development cubic structure all compounds was proved X-ray diffraction analysis. demonstrated that prepared materials exhibit squareness ratio (Mr/Ms) less than 0.5. This indicates presence multi domain particles which are appropriate for use transformer coils cores, resulting lower induction. morphology chemical composition composite confirmed FESEM EDS mapping FTIR analysis shows metal-oxygen bonds (Fe-O, Co-O) From studies, analyzed. dielectric parameters examined using analysis, revealing enhanced conductivity emphasizing multifunctional characteristics material, may render applicable diverse fields necessitating both features.

Polypyrrole (PPy)-doped bismuth calcium manganite (BCM) nanocomposites were synthesized by chemical polymerization. The amorphous nature of the polypyrrole and monoclinic crystal structure BCM particles (35–65 nm) confirmed various microstructural, X-ray powder, spectroscopy techniques. DC conductivity analysis via correlated barrier-hopping (CBH) model Mott’s variable-range hopping (MVRH) showed that exhibited ionic conduction. Activation energies, evaluated from Arrhenius plots, PPy/BCM-30 (30 wt.% BCM) had minimum value 0.09 eV, indicating maximum normal NTCR behavior, with resistance decreasing temperature. CBH described conduction process, AC measurements indicated was frequency-independent at lower frequencies but became dispersive frequency-dependent higher frequencies, conforming to Jonscher’s power law. study revealed transport electrical charge in material followed model. These results demonstrate how promising PPy/BCM are for energy storage, sensors, electronic materials.
