Crystal Structure of Solid Solutions LA1-xRxFeO3 (r=PR, nD)

Complex oxides with perovskite structure RFeO3, where R are rare earth metals, represent an important class of functional materials. RFeO3 compounds are used in thermoelectric devices, solid oxide fuel cells, as membranes for partial oxidation of methane and oxygen cleaning, as catalysts for CO oxidation and decomposition of NOx, and as sensory materials.

Crystal Strucrure of the Mixed Rare Earth Ferrites Pr0,5R0,5FeO3 (R = Nd, Gd, Tb, Dy, Ho)

The work deals with the study of the phase composition and crystal structure of new mixed ferrites Pr0,5R0,5FeO3 (R = Nd, Gd, Tb, Dy, Ho) obtained by solid state reactions technique. It was established that all samples synthesized adopt orthorhombic perovskite structure isotypic with GdFeO3.
