N2 - The present paper reports a study of ordered anisotropic cobalt nanoparticles arrays formed in mesoporous aluminosilicate matrices with pore diameters of 2 nm (MAS). The strategy of synthesis was based on intercalation of hydrophobic cobalt complex (Co2(CO)8) to the hydrophobic part of MAS/CTAB composite with subsequent reduction of metal. Ordering parameters and magnetic structure of nanocomposites were investigated by small-angle neutron scattering (SANS) and SQUID measurements. It was shown that the suggested method leads to formation of well-ordered magnetic nanowire arrays with periodicity of 4.32-4.37 nm. SANS studies indicate spatial correlation between magnetic and nuclear structure of nanocomposites. The composites demonstrate high blocking temperatures exceeding 300 K, large enough coercive force (up to 18,700 A/m) and saturation magnetization (16 A*m2/kg) at room temperature.
