| Résumé | The influence of Bi 3 on the structural and magnetic properties of the rare-earth-containing perovskites REFe 0.5Mn 0.5O 3 (RE=La,Nd) was studied, and the limit of bismuth substitution was determined to be x≤0.5 in Bi xRE 1-xFe 0.5Mn 0.5O 3δ (RE=La,Nd) at ambient pressure. Crystal structures in both La and Nd series were determined to be GdFeO 3-type Pnma with the exception of the Bi 0.3La 0.7Fe 0.5Mn 0.5O 3 sample, which is monoclinic I2/a in the a -b -b - tilt scheme. The samples undergo a transition to G-type antiferromagnetic order along with a weak ferromagnetic component, mixed with cluster-glass type behavior. The substitution of bismuth into the lattice results in a drop in T N relative to the lanthanide end-members. Long range ordering temperatures T N in the range 240255 K were observed, with a significantly lower ordered magnetic moment in the case of lanthanum (M∼1.71.9 μ B) than in the case of neodymium (M∼2.1 μ B). © 2011 Published by Elsevier Inc.
