A compound containing nitrogen is introduced into a solvent in which a metal carbonyl and a surface active agent are dissolved, and the solution is heated to generate a particle colloid or a magnetic fluid of a metal nitride. A particle colloid of a metal nitride with an even grain size, a good dispersibilitgy and a good fluidity, and a magnetic fluid thereof with an excellent properties are obtained with convenience and at high efficiency.

Method of manufacturing particle colloid or a magnetic fluid containing

A plasma CVD apparatus having a rotary vacuum reaction vessel, a starting gas introducing port, an ambient gas introducing port, an exhaust port, electrodes or an induction coil for applying a high-frequency electric field, and a cooling pipe provided in the starting gas introducing port for cooling the starting gas introducing port, wherein the starting gas introducing port and the exhaust port are located in opposition to each other on a rotating axis of the reaction vessel.
