中文摘要Solid state reaction method is used to synthesize Ba(Tii-xTMx)O3-delta (TM = Fe, Mn and Co) and (Ba1-ySry)(Ti1/3Fe2/3)O3-delta ceramics. The X-ray diffraction, scanning electron microscopy and transmission electron microscopy investigations reveal that structural evolutions from an orthorhombic BaTiO3 to a hexagonal Ba(Ti1-xTMx)O3-delta, a hexagonal to a rhombohedral in Ba(Ti1-xMnx)O3-delta, and a hexagonal to a pseudo-cubic transition in (Ba1-ySry)(Ti1/3Fe2/3)O3-delta are induced by increasing the doping concentration. Due to the oxygen vacancies derived from acceptor doping, nanoscale domains of incommensurate modulation (ICM) resultant are commonly observed in the hexagonal Ba(Ti1-xTMx)O3-delta compounds. The newly discovered rhombohedral Ba(Ti1/3Mn2/3)O3-delta having characteristic of face-sharing prism corner-connected by oxygen atoms is a typical example in searching for novel multiferroics. Discrepancies between the ionic radii of the B- and A-site dopants and that of Ti and Ba as a function of the doping concentrations, i.e., the effects of oxygen vacancies and the electronic configurations of the dopants, are concluded to be the driving forces for the structural transitions.
