“…It is worth mentioning that the conductivity of the films can also be influenced by oxygen vacancies, the concentration of which increases at higher synthesis temperatures. 7,37 Magnetic properties.-In Fig. 11a, it was found from isothermal magnetization measurements that films synthesized at 550 °C with different chromium concentrations exhibited a dependence on hysteresis loop shape.…”

Multiferroic materials, which exhibit simultaneous ferroelectricity, ferromagnetism, and ferro-elasticity, have attracted significant attention due to their multifunctional properties. Coupling between ferroelectric and magnetic properties has led to the development of non-volatile memory devices, transducers, magnetic field sensors, and other applications. Pb2Fe2O5 (PFO) is a promising multiferroic material due to it simultaneously exhibiting ferroelectricity and ferromagnetism at room temperature. Doping with aliovalent ions, such as Cr3+, has been proposed as an effective method for enhancing the ferroelectric and magnetic properties, consequently leading to the enhancement of multiferroic properties. The investigation shows that the lead ferrite phase (220) was present in all samples, but its abundance reduced with increasing synthesis temperature due to lead desorption. Dielectric measurements revealed that PFO films with highest Cr concentration had the highest polarization (Pr) of 72.2 μC cm−2. The study also found that the magnetization of PFO films was up to 9.5·10−7 μAm2 at an ambient temperature of 5 K, and the magnetic ordering temperature was 363 K, corresponding to the magnetic ordering temperature of chromium oxides. The morphology of Cr doped PFO films changed with increasing chromium content, resulting in a reduction in grain size and an increase in the film density.

“…The PTO is corresponding to standard card PDF#75-1605 (space group P4mm), and the NFO is corresponding to standard card PDF#74-2081 (space group Fd-3 m), shows that there is no obvious chemical reaction between the PTO and NFO in the prepared composite ceramics with the limitation of XRD resolution. Also, when the sintering temperature is 1050 °C, a obvious impurity peak can found, which is indexed as PbO 2 , this induced impurity may be because with the increase of sintering temperature, the concentration of Pb 2+ ions in the system gradually increased and then the reaction produced PbO 2 impurity peak, when the temperature further increased, the reaction of Pb 2+ ions in the system was completed, the existence of impurity may change the ceramic properties [16,22]. Figure 2 shows the SEM image of PTO/NFO composite ceramics with different sintering temperatures.…”

Magnetoelectric composites have attracted much attention due to their strong magnetoelectric coupling effect. In this paper, PbTiO 3-NiFe 2 O 4 (PTO/NFO) composite ceramics were prepared by sol-gel method. Effect of sintering temperatures on the structure, dielectric properties and multiferroic properties were studied. XRD results show that PTO/NFO ceramics have been successfully prepared. When the sintering temperature is 1050 °C, the secondary phase PbO 2 exists in the ceramics. SEM results show that there were two kinds of grains with different sizes. EDS analysis suggested that the large particles are NFO and the small particles are PTO. The sintering temperature has a great influence on the dielectric and ferroelectric properties of the prepared ceramics. When the sintering temperature is 950 °C, the ceramics show the maximum dielectric constant at low frequency. When the sintering temperature is 1150 °C, the maximum residual polarization is 1.236 μC/cm 2. The conductive mechanism of ceramics is dominated by Space Charge-Limited Conduction. The remanent magnetization and coercive field decrease with increasing the sintering temperature. The magnetoelectric coupling coefficient shows that ceramics have strong magnetoelectric coupling performance (5.7 V/cm•Oe).

“…Moreover, the aspects such as preferred orientation or surface strain can be considered as an additional powerful tool, allowing the physical properties of the materials to be tuned [18,19]. For the fabrication of multicomponent oxide thin films, various deposition approaches, including vacuum-based and non-vacuum based techniques, can be successfully employed [20][21][22][23][24]. It is well known that for some advanced deposition methods, such as metal organic chemical solution deposition, the precise stoichiometric control in multicomponent systems is a very challenging task because of different volatility of precursors, different deposition rates, etc.…”

In the present work, polycrystalline Bi0.67La0.33Fe0.5Sc0.5O3 thin films were synthesized using a simple and cost-effective chemical solution deposition process employing the spin coating technique. In order to check the feasibility of the fabrication of thin films on various types of substrates, the films were deposited on Pt-coated silicon, silicon, sapphire, corundum, fused silica and glass. Based on the results of thermogravimetric analysis of precursor and thermal stability study, it was determined that the optimal annealing temperature for the formation of perovskite structure is 600 °C. It was observed that the relative intensity of the pseudocubic peaks (001)p and (011)p in the XRD patterns is influenced by the nature of substrates, suggesting that the formed crystallites have some preferred orientation. Roughness of the films was determined to be dependent on the nature of the substrate.
