“…The Maxwell-Wagner interfacial or space charge polarization is also responsible for this manner [19]. The similar behavior is observed in the literature [16][17][18]. The ferrite expresses a small step like increase of dielectric constant at 700 K for 50 kHz and 0.1 MHz frequencies.…”

Ni 0.4 Mg 0.6 Fe 2 O 4 Ceramic samples were prepared by conventional double sintering approach and sintered at 1300 o C/4 h. These ferrites are further characterized using X-ray diffractometer. The diffraction study reveals that the present compound shows perfect single phase cubic spinel structure. In addition, the behavior of distinct electrical properties such as dielectric constant (ε'), dielectric loss (ε") and ac-conductivity (ζ ac ) as a function frequency as well as temperature is analyzed using the LCR controller.

“…It is a known fact that most of the ceramic titanate materials contain the cubic perovskite structure with a general chemical formula ABO 3, where 'A' atom is located at the corner position, 'B' atom occupies the body centre position and the oxygen atom prefers at the face centre position of the cubic unit cell [1][2][3][4][5][6][7][8][9][10]. In general, the barium titanate (BT) is a promising dielectric material exhibiting very attractive and tremendous applications caused due to the low particle size [11].…”

Ba 0.4 Cu 0.6−x La x TiO 3 (x=0.2, 0.4 & 0.6) (BCLT) nanoparticles were prepared by hydrothermal method. The x-ray diffraction (XRD) pattern established the existence of tetragonal phases. The nanospheres were observed in the surface morphology of present materials using the transmission electron microscopy (TEM). The optical properties were investigated to confirm the presence of metal oxide bonds as well as the optical band-gap energy of BCLT nanoparticles. The dielectric and impedance parameters were studied as a function of frequency and composition. The Cole-Cole plots were drawn to understand the microstructure and electrical conduction mechanism. In addition, the ferroelectric nature was carried out with the help of polarization versus electric field (P-E) loop tracer. Materials and methodsBa 0.4 Cu 0.6−x La x TiO 3 (x=0.2, 0.4, & 0.6) nanoparticles were synthesized via hydrothermal technique. The flow chart for the preparation of BCLT samples was depicted in figure 1. The starting raw materials of Ba (NO 3 ) 2 .6H 2 O

“…12 shows the Cole-Cole plots of STO sample at room and other higher temperatures. The grain effects in the samples are indicated by presence of semicircle; furthermore, the decrement in semicircle radius with increasing temperature can be observed; inferring the decrease in the resistivity with rise of temperature 26 .…”

“…10(a) and 10(b) respectively. It can be easily depicted that ac conductivity for the SrTiO 3-d sample was almost constant at lower frequencies; while at higher temperatures and frequencies there was sharp enhancement in ac conductivity acquiring approximately 4.6 x 10 -4 value at frequency 1MHz and temperature 400 o C; this increase may be due to the strong hopping mechanism 26 . It can be easily depicted from the curves that Z'' values show a maximum value at low frequency which decreases with temperature.…”

Pure strontium titanates have been successfully fabricated in this work via sol gel route. The obtained powders were calcined at various temperatures and effects of calcination and sintering on phase development, crystallite size, lattice parameters, microstructure etc. were investigated by XRD and SEM techniques. The development of phase with temperature has been investigated using DTA/TG technique. The dielectric and electrical parameters were analyzed and effects of temperature and frequency variation on these parameters were studied.
