摘要：

Gamma-Fe2O3 small particles (less-than-or-equal-to 10 nm) with various dispersion rates were studied by static magnetic measurements at low and medium applied fields. The results raise various questions concerning the determination of the non-relaxing magnetic moment and of the particle volume, the role of the particle surface and interactions.
