Structural and magnetic study of RFe0.5V0.5O3 (R=Y, Eu, Nd, La) perovskite compounds

► RFe0.5V0.5O3 show a simple perovskite structure with a+b−b− tilting of octahedra in the Pbnm space group as RFeO3 and RVO3. ► Antiferromagnetic ordering of spins of the Gz type are observed with TN around 300 K. ► Partial but not conclusive Fe/V cation ordering is suggested by NPD data for R=La.
