Abstract
In a method of producing magnetic particles which includes the steps of preparing alloy particles capable of forming a CuAu or CuAu hard magnetic ordered alloy phase and of forming magnetic particles for forming CuAu or CuAu magnetic particles, a plurality of solutions Land Lfor preparing the alloy particles are passed in a thin-plate laminar flow and diffused in the direction perpendicular to the flow direction at the contact interface of the solutions Land Lin a mixing channel by using a microreactor, whereby a uniform mixing reaction is conducted in a short time.
