The X-Ray Diffraction (XRD) analysis and Rietveld refinements confirmed the presence of a single tetragonal phase for the pure and doped samples. The SEM study revealed that the microstructure is highly susceptible to the addition of both dopants, causing an evident grain refinement. On the other hand, the addition of Sn4+ and Cr3+ had a strong influence on ferroelectric properties, as observed by the pinching of the ferroelectric hysteresis loops. The addition of Sn4+ increases the remnant and maximum polarization, as the Cr3+ doping promoted the contrary effect. Co-doping with Sn4+ and Cr3+ resulted in a maximum energy storage value of 0.2574J/cm3 with a efficiency of up to 65%, overcoming the values of pure BT.

We provide the sophisticated and phenomenological discussions on the magnetoresistivity measurement results in three main sections along the paper.

The vanadium addition promotes thermally the movement of correlated two-dimensional (2D) pancake Abrikosov vortices between the in-plane Cu–O2 layers in the valance band, vortex lattice elasticity, vortex dynamics, distance for interlayer Josephson couplings and flux pinning centers and the theoretical computations confirm the remarkable degradation in the formation of super-electrons in the Bi-2223 crystal system.
