Synthesis, physic and structural characterization of rare-earth oxynitrides REFeO3-xNx (RE=La, Pr, Nd, Sm)

This work studies the synthesis of the perovskite oxynitrides REFeO3-xNx (RE=La, Pr, Nd, Sm). For comparison purposes and as precursors in some of the synthesis reactions studied; their respective oxides, the orthoferrites REFeO3 (RE=La, Pr, Nd, Sm), have been synthetized by the self-combustion glyc...
