Influence of iron addition on the oxygen-deficient Sr0.85Bi0.15Co1-xFexO3-d (0.0<x<1.0) perovskites
Artikel i vetenskaplig tidskrift, 2008

A series of oxygen-deficient Sr0.85Bi0.15Co1-xFexO3-d (0.00.8. Evidence of weak superstructures, reflecting local oxygen ordering, is also obtained from electron diffraction. For all oxygen-annealed phases the average structure reverts to cubic Pm-3m. The as-prepared samples show G-type antiferromagnetic order at room temperature. The oxygen annealed x = 0.10, 0.25 and 1.0 samples display low-temperature spin-glass transitions.
