“…Since the cationic size of Ag 1+ (1.26 °A) is smaller than the Cd 2+ (0.97 °A), so the expansion of crystal size after incorporating the Ag contents in CdS thin films is our expected result as we extracted from XRD data. The crystallite size was calculated using Sherrer formula [13]:…”

“…Exchange near the oxygen vacancies is negative according to Goodenough-Kanamori empirical rules. Oxygen vacancies should lead to the formation of a weak magnetic state like a spin glass one [6,23]. Variation in charge carrier concentration with the change in temperature generates current.…”

Site occupancy plays an important role in the properties of the materials in general, and in the case of ferrites, this makes a significant effect. Barium ferrite has a wide range of applications ranging from everyday applications to sophisticated communication technologies. Two compositions Ba 1−x Pb x Fe 12 O 19 and BaPb x Fe 12−x O 19 (x = 0.0-1.0) were synthesized by co-precipitation method using similar synthesis conditions. The aim was to understand the different behaviors when Pb replaced Ba in R and R * blocks in the first composition, while in the second composition it replaced iron in RSR * S * blocks. Microstructural and morphological variations in both synthesized compositions because of Pb dopant were responsible for affecting all properties. Higher ionic radius (1.76 Å), lower melting point (950 °C) of lead and gradually increased concentration were responsible for generating stresses and distortions of different magnitudes in both compositions. Magnetic and DC electrical characterizations were investigated by applying similar conditions. Higher phase purity and better morphology are obtained when Ba is replaced by Pb. Strong variation in coercivity due to decrease in anisotropic energy is useful in high-density storage devices. For the other composition, when Fe is replaced by Pb, higher resistivity is obtained. The obtained range of resistivity is useful against eddy current losses in high-frequency devices.
