The influence of structural disorder on the magnetic properties of Sr2Fe1-xGaxTaO6 (0 <= x <= 1)

Abstract:

Powder samples of the magnetically diluted cubic perovskite phases Sr2Fe1 - xGaxTaO6 have been prepared by high temperature ceramic methods. X-Ray powder diffraction data show that the cations occupying the 6-coordinate site are chemically disordered in the range 0.10 ≤ x ≤ 0.40 and that increasing the Ga3+ concentration above this value leads to partial cation ordering between Ga3+ and Ta5+. Magnetic susceptibility data collected irom these compounds can be fitted to the Curie-Weiss law, res...
