摘要: The multiferroic solid solution of (1−x)[0.9BiFeO3–0.1DyFeO3]–xPbTiO3 with compositions around the morphotropic phase boundary has been synthesized in form ceramics and characterized by Piezoresponse Force Microscope (PFM) Superconducting Quantum Interference Device. Both original local polar domain structure evolution after poling have studied PFM. PFM imaging revealed some interesting details switching process: out-of-plane image shows a uniform direction polarization along applied electric field, while in-plane indicates two kinds domains antiparallel polarizations. This kind poled is explained based on orientations as permitted rhombohedral crystal symmetry grains different crystallographic orientations. magnetic properties measured within temperature range from 1.8 K to 300 K reveal an sequence transi...
