摘要：

Ultrasmall magnetic particles containing iron have been prepared by reduction of iron ions by the use of sodium in mercury. Mössbauer studies at 12 K show that the magnetic hyperfine field is significantly larger than in bulk α-Fe, suggesting that an iron mercury alloy rather than α-Fe has been formed. The particles exhibit superparamagnetic relaxation above 120 K.
