Nano-magnetic particles are constructured with magnetic transition metal or alloy nano-particles embedded in non-metallic medium, which contain the advantages of two types of material. Nano-magnetic particle is a multi-functional magnetic material and has wide applications in many fields, such as magnetic recording, ferrofluids, catalysis, medicine and pigment. In this paper, some items about nano-magnetic particles were introduced. Firstly, the preparation methods including precipitation, hydrothermal method, micro-emulsion, sol-gel, colloidal particles template, polyol reduction method, displacement method and characteristics of nano-magnetic particles were introduced. Secondly, the surface modification methods and characterization of nano-magnetic particles were described. Finally, the research prospect of nano-magnetic particles was presented.
