Abstract

Perovskite derivatives Ba₃LnFe₂O_7.5 can be described as an assemblage of double “FeLn” chains of isolated FeO₄ tetrahedrons and YO₆ octahedrons, interconnected through dimeric tetrahedral Fe₂O₇ groups. Long range antiferromagnetic ordering, with T_N ranging from 6.2 K for Y to 12.5 K for Dy, is observed in spite of the isolated character of iron.
