Preparation and Properties of a Stable Metallic Ferrofluid.

Abstract

The aim of this research work has been to characterise the properties of suspensions of small single domain iron particles in mercury. These ferromagnetic liquids have been stabilised against diffusional growth by tin, antimony, and sodium additives. That the tin, antimony, and sodium associate themselves with the iron particles to form coatings is strikingly shown in this report by resistivity and latent heat of melting experiments.
