  "description": "<p>Single-phase strontium ferromolybdate (Sr2FeMoO6&ndash;&delta;) samples with different degrees of the superstructural ordering of the Fe/Mo cations were obtained from partially reduced SrFeO3&ndash;\u0445, SrMoO4 precursors by the solid-state technology. The study of the temperature dependences of the magnetization measured in the field-cooling and zero-field-cooling regimes indicated an inhomogeneous magnetic state of the samples. The presence of magnetic regions of different nature has also been revealed by the small-angle neutron scattering. For the Sr2FeMoO6&ndash;&delta; samples with different superstructural ordering of the Fe/Mo cations and for all values of the magnetic field induction in the range up to 1.5 T and of the scattering vector in the interval 0.1 &gt;q &gt;0.005 &Aring;&ndash;1, the analytical dependence I ~ q&ndash;&alpha; obeys the Porod law (&alpha; &asymp; 4), which corresponds to an object with a smooth and well-marked surface and polydisperse grain size. Deviations from the Porod law in the q &gt; 0.1 &Aring;&ndash;1 region and a weakening of the neutron scattering in applied magnetic fields may be ascribed to magnetic inhomogeneities with diameters D &lt;6 nm, which are partially destroyed /oriented by magnetic fields \u0412 &ge;1.5 T.&nbsp;</p>",
