“…47 This also shows good agreement with Koop's theory. 48 Along with this, Gddoped hematite NPs were found to have higher values of dielectric constants than hematite NPs. This is due to the doping with Gd 3+ that can generate crystal defects which create imperfections in the alignments of the crystal as the Gd 3+ ion is larger than Fe 3+ , creating stress inside the host lattice which also shows agreement with the XRD data.…”

“…This development is owing to the better structural ordering that can have takes place at the superior calcination temperatures and the elevated concentration of the charge carriers i.e., [Mn 3+ ] and [Mn 4+ ]. [33][34][35] Figures 5a and 5b illustrate the conductivity pattern of LM calcined at 600 °C and 700 °C. Frequency vs σ of LM indicates that when the temperature raises the conductivity of the sample too increases at elevated temperatures.…”

Lithium manganate (LM) has been extremely well established as a material for applications in electronic devices such as personal organizers, pagers, personal computers, facsimile machines, portable stereophonic equipment, and cellular phones. LM nanoparticles have been prepared via the sol-gel method through a stoichiometric quantity of Manganese acetate tetrahydrate, Lithium hydroxide monohydrate, and Citric acid anhydrous taken in 1:2:3 ratios. The calcination was done with the resulting powder samples at different temperatures of 600 °C and 700 °C. The LM powder samples were utilized for dissimilar characterizations for FTIR spectral analysis exhibiting the presence of functional groups. PXRD result illustrates that the “h, k, l” values are well matched by the earlier reported values. The dielectric properties are calculated at different temperatures from 50 °C to 350 °C. When the calcination temperature increases the conductivity of the sample also increases. The dielectric loss and dielectric constant confirm the normal dielectric behavior of the material. XPS results show the measured empirical formula, elemental composition, and electronic state of the elements in a material. Photoacoustic spectroscopy analysis of the title compound values makes it a promising material for Li-ion battery and electrical storage devices applications.

“…A wide variety of practical applications are made possible by many intrinsic perovskite materials features due to the continuous interaction between structure and properties. Ferroelectricity [ 2 , 3 , 4 ], semi-conductivity [ 5 , 6 ], superconductivity [ 5 , 6 ], piezoelectricity [ 7 , 8 ], thermoelectricity [ 9 ], colossal magnetoresistance, ferromagnetism [ 10 ], and half-metallic transport [ 11 , 12 ] are just some of the fascinating physical and chemical properties of perovskites. These oxides are increasingly being used in electronic and magnetic materials, automotive exhaust, water splitting catalysts, fuel cells, battery electrode materials [ 13 ], gas sensors, humidity sensors, microwave devices, high-density data storage, magnetic ferrofluids, magnetic switches, MRI, high-frequency, and power devices are among the applications for these materials [ 2 ].…”

A high perovskite activity is sought for use in magnetic applications. In this paper, we present the simple synthesis of (2.5% and 5%) Tellurium-impregnated-LaCoO3 (Te-LCO), Te and LaCoO3 (LCO) by using a ball mill, chemical reduction, and hydrothermal synthesis, respectively. We also explored the structure stability along with the magnetic properties of Te-LCO. Te has a rhombohedral crystal structure, whereas Te-LCO has a hexagonal crystal system. The reconstructed Te was imbued with LCO that was produced by hydrothermal synthesis; as the concentration of the imbuing agent grew, the material became magnetically preferred. According to the X-ray photoelectron spectra, the oxidation state of the cobaltite is one that is magnetically advantageous. As a result of the fact that the creation of oxygen-deficient perovskites has been shown to influence the mixed (Te4+/2−) valence state of the incorporated samples, it is abundantly obvious that this process is of utmost significance. The TEM image confirms the inclusion of Te in LCO. The samples start out in a paramagnetic state (LCO), but when Te is added to the mixture, the magnetic state shifts to a weak ferromagnetic one. It is at this point that hysteresis occurs due to the presence of Te. Despite being doped with Mn in our prior study, rhombohedral LCO retains its paramagnetic characteristic at room temperature (RT). As a result, the purpose of this study was to determine the impacts of RT field dependency of magnetization (M-H) for Te-impregnated LCO in order to improve the magnetic properties of RT because it is a low-cost material for advanced multi-functional and energy applications.
