摘要：

Despite the high prominence of the perovskites BiFeO3 and KNbO3 the solid solution between the two has received little attention. We report a detailed neutron and synchrotron X-ray powder diffraction, and Raman spectroscopy study which demonstrates an R3c -> P4mm -> Amm2 series of structural phase transitions similar to that exhibited by the PbZrO3-PbTiO3 solid solution.
