چکیده انگلیسی
We have prepared a composite BaTi0.9Zr0.1O3 (BTZr) doped with Li0.5Fe2.5O4 (LF) having chemical formulae (1- x) BTZr + (x) LF (x=0, 0.05, 0.1 and 0.15) conventional solid state reaction technique. We have sintered the grown composites at 1150â¯Â°C for 3â¯h. We have characterized the grown composites using XRD, FESEM, P-E loop tracer and LCR meter. The XRD measurements reveal the tetragonal nature of the composites. The morphological studies reveal that the composite exhibits dense microstructure with small pores. The P-E loops confirm that the composites exhibit remnant polarization and the coercive field increases with increasing concentration of Lithium Ferrite (LF). We have studied dielectric property of the composites by varying the temperature of the sample from 30â¯Â°C to 500â¯Â°C at 1â¯kHz, 10â¯kHz and also by varying the frequency from 1â¯Hz to 10â¯MHzâ¯at 30â¯Â°C. The dielectric property of BTZr has increased after doping LF in BTZr which reveals the enhancement of electrical properties of the grown composite.
