ABSTRACT:
Electrically-conductive superparamagnetic liquid colloids and methods for making and using them are described. The magnetic liquid colloids contain magnetic particles coated with conductive, organio-metallic compund, which impart the magnetic and conductive characteristics to the fluid. The coated magnetic particles are dispersed in a carrier fluid that gives the fluid viscosity, flow and vapor pressure properties.
