Impact of Crystallite Size and Phase Boundaries on Magnetic and Thermoelectric Properties of Cu-Added BiFeO₃.

ABSTRACT: In this study, bismuth ferrite (BFO) and copper-added BFO were synthesized using the coprecipitation method. The incorporation of copper into the BFO lattice led to a reduction in the phase percentage of BFO due to the early formation of CuBi₂O₄. X-ray diffraction analysis revealed a decrease in crystallite size up to 0.1 CBFO, followed by an increase. This reduction in crystallite size causes an imbalance between the spins of the sublattices, resulting in an antiferromagnetic core/ferromagnetic shell (AC/FS) structure. The uncompensated spins generated by the decreasing crystallite size weaken the ferromagnetic properties with the addition of Cu. Additionally, the reduction in crystallite size leads to decreased electrical conductivity due to carrier scattering, with
