Abstract: The effect of parabenzoquinone molecule adsorption on the magnetic properties of nanostructured silicon is studied. A mesoporous silicon sample with a specific surface area of $\sim$800 m$^2$/g was used as nanostructured silicon. It is found that parabenzoquinone molecule adsorption on a porous silicon surface results in the formation of a new nanocomposite material, i.e., a porous silicon matrix filled with clusters of exchange-coupled adsorbed molecules. The superparamagnetic behavior of this nanocomposite is detected. It is shown that the saturation magnetic moment remains unchanged in the temperature range from 100 to 360 K and does not degrade in air.
