| description | The samples with chemical formula La1-xMgxMn0.4Ti0.6O3 (x = 0.30, 0.40 and 0.50) were synthesized using solid-state reaction
method. XRD of the samples shown the samples pattern attributed to the cubic structure with ‘a’ = 3.8943 and its space group
Pm3m. The SEM images display microstructure of the sample were porous and the grains are merged with unequal sizes
distributed inhomogeously throughout the samples with irregular boundaries. The sample of x = 0.4 was the most porous than
the others. The electrical properties were measured using LCR meter with the frequency range from 0.01 Hz until 100 KHz
and in a temperature range of 313 K until 373 K. The electrical properties of the samples were study by analyzed the dielectric
constant, ε’, dielectric loss, ε”, and tan δ. The results for dielectric constant and dielectric loss showed the higher values were
located at lower frequency region which suggest that the samples were having interfacial polarization. Tan δ shows the lower
value at higher frequency and lower temperature. By doping Mg, it decreases the dielectric loss and increasing the Mg doping
it increases the dielectric constant. |
