Magnetic recording medium, and method for producing the same |
摘要 |
A magnetic recording medium including: a support; and a magnetic layer provided on the support, the magnetic layer containing a magnetic particle of a CuAu type or Cu<SUB>3</SUB>Au type ferromagnetic ordered alloy phase, wherein a content of boron in the magnetic particle is 0 to 0.9 at %, and a content of fluorine in the magnetic particle is 0.09 to 0.3 at %. Also provided is a method for producing a magnetic recording medium including: forming an alloy particle capable of forming a CuAu type or Cu<SUB>3</SUB>Au type ferromagnetic ordered alloy phase by a reduction method in which a reducing agent containing a boron atom is used; forming a layer including the alloy particle on a support; heat-treating the alloy particle at a temperature below a transformation temperature of the alloy particle; and annealing the alloy particle at a temperature which is not lower than the transformation temperature of the alloy particle.
