Abstract:
The present invention relates to ferromagnetic metal particles having an average major axis diameter (L) of 10 to 100 nm which satisfy a relationship between the average major axis diameter (L) and a particle SFD represented by the following formula: Particle SFD≦0.0001 L2−0.0217 L+1.75; a process for producing the ferromagnetic metal particles; and a magnetic recording medium using the ferromagnetic metal particles.
