Abstract

The Fe-Co double nanoparticle magnetic fluid prepared by pulse laser deposition was investigated. The results show that peak height of magnetic fluid under 5000 Gs magnetic fluid gradually reduced with increase mass ratio of Fe(CO)5 and Co2(CO)8, and peak height is biggest when mass ratio of Fe(CO)5 and Co2(CO)8 is 5:1. It is can seen that magnetic fluid consist of Fe3O4 and CoFe2O4 particle. The particles uniform covered surfactant in magnetic fluid and favorable distribution with most particle size is approximate 14 nm. The magnetic fluid is super paramagnetic functional materials with magnetic saturation of the 0.025 T. The friction coefficient of magnetic fluid rapidly decreases than paraffin oil with increase of rotational speed and friction time lubricated.
