摘要:
Bi0.9Ho0.1Fe0.95 Cr0.05O3 (BHFCO) ceramic was synthesized by the solid-state reaction method. BHFCO ceramic has a perovskite rhombohedral R3c structure proved by XRD measurements, and the lattice parameter was smaller than BiFeO3. The dielectric properties test and the differential scanning calorimetry show BHFCO ceramic exhibits a strong relax ferroelectric feature and the Neel temperature is 315°C. Well room temperature saturated ferroelectric hysteresis loops has been observed, and the remanent polarization is around 20.25 μC/cm2. X-ray photoelectron spectroscopy proves the valence states of Fe ions of BHFCO ceramics is 3+. Well room temperature saturated ferromagnetic hysteresis loops also has been observed, and the remanent magnetization and saturation magnetization are 0.476 A·m2/kg and 2.290 A·m2/kg respectively.
