AMOURI, D. Dhruv, W. DIMASSI This is a preprint; it has not been peer reviewed by a journal. https://doi.org/ 10.21203/rs.3.rs-9331060/v1 This work is licensed under a CC BY 4.0 License Status: Posted Version 1 posted You are reading this latest preprint version Abstract The polycrystalline ceramic synthesis was obtained through a solid-state reaction under a controlled atmosphere. The X-ray diffraction Rietveld refinement showed a rhombohedral R3c structure for all our ceramics. Room temperature M vs. H and P vs. E hysteresis loops revealed improved magnetic and ferroelectric properties due to Praseodymium substitution. The ceramic presents attainable saturated hysteresis loops with a spontaneous polarization (P s ) of 18.05 µC/cm 2 . Pr substitution enhances magnetization, reaching the uppermost remnant magnetization (M r ) of 6.73 emu/g for x = 0.025 composition. Moreover, Both T c and T N shifted closer to room temperature and approached each other for ceramics, indicating enhanced magnetoelectric coupling. At room temperature, the highest value of α ME was obtained for the optimum ceramic: before electrical poling, α ME was of 1.526 mVcm −1 Oe −1 . The interesting features suggest the magnetoelectric ceramics as a potent candidate for a wide span of modern applications Multiferroïcs Ceramics Bismuth ferrite Magnetic Ferroelectric Magnetoelectric coupling Full Text Additional Declarations No competing interests reported.
