摘要：
Lorentz microscopy is applied to observe the magnetic structures of Fe fine particles in granular films. Observed particles, 20-60 nm in diameter, are prepared by precipitation in an Fe-Mo amorphous thin film. In order to understand accurately the observed Lorentz micrographs, image contrast is simulated mimetically. Some analyses for single-magnetic-domain particles rue shown in comparison with experimental data. The minimum size of the observable Fe particle is thought to be about 10 nm in diameter.
