Abstract
The σ (T) of fine iron particles in the field of 4 T and 2 T are measured in the temperature rising and dropping process. It is found that the σ (T) increase anomalously as the temperature and are irreversible. It can be explained by spin pinning in the surface oxide layer of fine iron particles.
