ABSTRACT

With Fe addition, the

crystal structure change from tetragonal (without Fe) (space groupP4/mmm) to

hexagonal (space group P63/mmc). The grain size increase with increasing of Fe

contained in BaTiO3 which is confirmed by Scanning Electron Microscope

(SEM). Electrical behavior (impedance as a function of frequency) of Ba(Fe,Ti)O3

shows grain and grain boundary contribution. Differential Scanning Calorimetric

(DSC) shows that with Fe addition, the Curie temperature increases from ~ 1200C

in BaTiO3 to ~1700C-1750C in Ba(Fe,Ti)O3., A study on impedance spectroscopy of Ba(Fe,Ti)O3 has been done. In this

research, electrical behavior ware analysed by using impedance spectroscopy

method. Ba(Fe,Ti)O3 prepared by solid state reaction method. XRD

characterization shows that all sampel are single phase. With Fe addition, the
