摘要：

Volume determination of cosputtered Fe-Al2O3 small particles have been performed from magnetization measurements in low and medium fields (H ≤ 18 kOe). The low field approach seems less reliable than the medium field one because of difficulties inherent to the value assigned to the magnetic moment of the non-relaxing particle and its thermal variation. © 1990.
