    <description descriptionType="Abstract">&lt;p&gt;Single-phase strontium ferromolybdate (Sr2FeMoO6&amp;ndash;&amp;delta;) samples with different degrees of the superstructural ordering of the Fe/Mo cations were obtained from partially reduced SrFeO3&amp;ndash;х, 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&amp;ndash;&amp;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 &amp;gt;q &amp;gt;0.005 &amp;Aring;&amp;ndash;1, the analytical dependence I ~ q&amp;ndash;&amp;alpha; obeys the Porod law (&amp;alpha; &amp;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 &amp;gt; 0.1 &amp;Aring;&amp;ndash;1 region and a weakening of the neutron scattering in applied magnetic fields may be ascribed to magnetic inhomogeneities with diameters D &amp;lt;6 nm, which are partially destroyed /oriented by magnetic fields В &amp;ge;1.5 T.&amp;nbsp;&lt;/p&gt;</description>
