چکیده
The Co0.7-xNixMn0.3Fe2O4 (CNMFO) ferrites with x = 0.00, 0.05, 0.10 and 0.15, PbZr0.52Ti0.48O3 (PZT) ferroelectric 30% CNMFO – 70% PZT magnetoelectric (ME) composites were synthesized by double sintering ceramic method. XRD confirmed the pure phase formation of all compositions ferrite, ME composites. All ferrites, show negative temperature coefficient resistance (NTCR) confirming semiconducting behavior, though conduction mechanism is quite different than known semiconductors such as, silicon germanium. conduction, due to electron hoping in against polaron explained. effect cation distribution on resistivity ferrite also discussed. Thus, as well has been discussed dielectric constant effective combined constituent phases studied.
