The present invention relates to a method of producing anmagnetic particle including forming a layer containing an alloynparticle that can form CuAu type or Cu 3 Au type hard magneticnorder alloy phase on a support, oxidizing the layer, and annealingnthe layer in non-oxidizing atmosphere. The invention also relatesnto a method of producing a magnetic particle including producingnan alloy particle that can form hard magnetic order alloy phase,noxidizing the alloy particle, and annealing the particle in non-oxidizingnatmosphere, and a magnetic particle produced by thenforegoing production method. Further, the invention relates to anmagnetic recording medium comprising a magnetic layerncontaining a magnetic particle and a method of producing anmagnetic recording medium including forming a layer containingnan alloy that can form the foregoing hard magnetic order alloynphase, oxidizing the layer, and annealing the layer in non-oxidizingnatmosphere. |
