Abstract

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 alpha-Fe, suggesting that an iron mercury alloy rather than alpha-Fe has been formed. The particles exhibit superparamagnetic relaxation above 120 K. Journal of Applied Physics is copyrighted by The American Institute of Physics.
