摘要

Multiferroic BiFeO₃ (BFO) and Y, Zr codoped BFO (Bi_1-xY_xFe_0.95Zr_0.05O₃) ceramics were prepared and the influence of codoping on the crystal structure and magnetic properties were investigated in this work. Confirmed by the evolution of X-ray diffraction and Raman modes, the codoping has changed the crystal structure from rhombohedral to tetragonal in bulk BFO ceramics. The enhancement of magnetic behaviors is demonstrated by the damage of space-modulated spiral spin structure, and it can be attributed to the crystal structure change and size effects. Meanwhile, Raman spectra from 300 to 800K demonstrates that lower frequency phonon modes show rapid softening near the Neel temperature.
