The samples exhibit an orthorhombic crystal structure and the volume of the unit cell decreases with the addition of cobalt nanoparticles, indicating that Co+3 ion diffuses from the intergranular region into the unit cells. The suppression of the onset of superconductivity and magnitude of diamagnetism is observed in AC-susceptibility measurements showing magnetic scattering from the charged particles induced by doped Co+3 atoms into the unit cell. The doping of unit cells with Cobalt nanoparticles from the inter-grain regions is confirmed by a shift in the peak position and intensity of various oxygen modes in FTIR absorption measurements. Excess conductivity analysis of conductivity data has shown an increase in the coherence length along the c-axis, the Fermi velocity of the carriers, and the energy required to break the Cooper-pairs with the addition of Co nanoparticles. The observed increase in the values of these parameters is likely associated with an increase in the density of charge carriers in the conducting copper oxide planes.

In this study, an efficient method of atmospherically hydrothermal assisted solid-state synthesis for ultrafine BaTiO3 particles is presented. The BaTiO3 nanopowders with homogeneous distribution, a mean particle size ~ 260 nm and high tetragonality of 1.0095 were obtained by at the optimal parameters of hydrothermal time of 6 h, Ba(OH)2·8H2O/BaCO3 = 0.25/0.75 and calcination temperature of 1000 oC. XRD and HRTEM analyses revealed a “core-shell” structure of TiO2@BaTiO3 formed in the first-step hydrothermal process, which reduces the diffusion distance between BaCO3 and TiO2, resulting in a lower calcination temperature at the second-step solid-state reaction. Compared with pure hydrothermal and solid-state reaction processes, the atmospherically hydrothermal assisted solid-state synthesis in this study shows larger ability for improving the particle size distribution and the tetragonality, reducing defects of BaTiO3 particles. In particular, the grain size, sintering density, and dielectric constant at the Curie temperature of BaTiO3 ceramics are 1.93 μm, 98%, and 7066, respectively. In the solid-state reaction stage, the lattice diffusion distance from BaO to TiO2 tends to decrease due to the formation of BaTiO3 shells, thus, high tetragonal and relatively small particle size of BaTiO3 powder was synthesized.
