Abstract: In this work the amorphous nanopowder SiO2 with a specific surface 154 m2/g was produced by the method of pulsed electron beam evaporation of target from pyrogenic amorphous NP Aerosil 90 (90 m2/g). Nanoparticles of NP SiO2 showed the improved magnetic and thermal properties in comparison with NP Aerosil 90. Possible reasons of emergence d0 ferromagnetism at the room temperature in amorphous NP SiO2 are discussed.

Keywords: pulsed electron beam, nanopowder 2 SiO , Aerosil 90, 0 d ferromagnetism 2 SiO
