Small angle neutron scattering and magnetization data were utilized for revelation of internal structure of advanced nanocomposite containing Fe2O3 nanoparticles embedded in regular pores of amorphous silica matrix SBA15. Experimental data were analyzed based on appropriate models and the parameters obtained were compared to structural and magnetic characteristics of the system obtained employing other methods. Excellent agreement of the results suggests that mutual application of the methods can provide reliable information about the structures buried in the body of the composite.
