Magnetization, resistance and Hall effect are studied in granular magnetic Co-SiO2 nanocomposites in the temperature range 5-300 K and fields up to 6 T. Relative contributions from spin-independent and spin-dependent processes to the giant Hall effect near the metal-insulator transition are analysed.
