| titleOfInvention | Ferromagnetic metal powder and magnetic recording medium using the same |
| abstract | (57) [Summary] [Problem] To produce a ferromagnetic metal powder having a small thermal fluctuation, and to use the powder to have excellent practical properties such as preservability, a short wavelength output and a good C / N ratio, and a thermal fluctuation. To provide a magnetic recording medium whose characteristics do not deteriorate. A ferromagnetic metal powder comprising iron as a main component, a metal portion and an oxide layer present around the metal portion, the ferromagnetic powder having an average major axis of 30 to 65 nm, and a coefficient of variation thereof. Is 3 to 25%, and the average needle ratio is 4.0 to 4.0. 8.0, the ratio of the crystallite size of the ferromagnetic metal powder to the average minor axis of the metal part is 1 to 4, the coercive force of the ferromagnetic metal powder is 135 to 240 kA / m, magnetization ([sigma] s) is a ferromagnetic metal powder and a magnetic recording medium using the same, characterized in that a 90~155A ยท m 2 / kg. |
