High-resolution neutron powder diffraction study on the structure of BaPbO3
چکیده انگلیسی
Using high-resolution time-of-flight neutron powder diffraction, the crystal structure of BaPbO3 has been reinvestigated at room temperature and 4.2 K. By comparing different structural models, i.e. the orthorhombic Imma and the monoclinic I2/m, it is concluded that the former one describes correctly the structure of BaPbO3, and no Imma→I2/m phase transition exists in the temperature range investigated. The apparent monoclinic distortion is likely due to the existence of twins that introduce the micro strain resulting in anisotropic line broadening of the observed profiles.
