摘要: The crystal structure of metastable LuFeO3 synthesized by containerless processing has been revealed to be a non-centrosymmetric (space group P63cm) analyzing the high-energy synchrotron-radiation powder-diffraction data using maximum entropy method (MEM)/Rietveld method. structural characteristics are found in FeO5 trigonal bipyramid distorted and tilted from c-axis, which is cause hybridization atomic orbitals between O atom constituent polyhedron neighboring Lu atom. spontaneous polarization expected polar estimated at about 5 µC/cm2.
