MAGNETIC PROPERTIES OF GRANULAR Fe-SiO FILMS

  • Published : 1995.10.01

Abstract

Granular Fe-SiO films were prepared by co-evaporating in a vacuum. Magnetic properties of the films were investigated by $M\"{o}ssbauer$ and magnetization measurments. The $M\"{o}ssbauer$ data suggest that the films consist of amorphous Fe-Si alloy particles with the size of nanometers. Superparamagnetic magnetization curves were well reproduced by considering the distribution of particle size and the magnetic dipole interaction between particles as the mean field.
