Abstract
Magnetization. resistance and Hall effect are studied in granular magnetic Co-SiO2 nanocomposites in the temperature range 5-300K and fields up to 6T. Relative contributions from spin-independent and spin-dependent processes to the giant Hall effect near the metal-insulator transition are analysed. (C) 2001 Published by Elsevier Science B.V.
