The magnetooptical and magnetic properties of porous silicon containing ele
ctrochemically incorporated cobalt microgranules were studied. It was found
that the granular cobalt-porous silicon nanocomposites exhibit ferromagnet
ic properties. The nanocomposite with a cobalt content of 10% showed anomal
ously high magnitude of the equatorial Kerr effect. (C) 2001 MAIK "Nauka/In
