Specific features of the structure and electrical conductivity of the magnetically ordered oxide (La0.9Sr0.1)(Fe0.8Mg0.2)O3-y
Artikel i vetenskaplig tidskrift, 2008

The structure of the (La0.9Sr0.1)(Fe0.8Mg0.2)O-3 (-) (y) oxide is investigated using neutron diffraction at temperatures of 10, 295, 500, 700, and 1000 K. The results of the structure refinement are in good agreement with the experimental data on the electrical conductivity and confirm the inference that the oxidation state of iron cations is higher than 3+ and that the structure of the compound is antiferromagnetically ordered at temperatures below 500 K.
