Use of a powder composition and a medium |
| abstract |
The invention relates to the use of a powder composition comprising at least 95% by weight of magnetite (Fe3O4) particles as a magnetisable component in a medium for magnetically storing information. At least 99,9% by weight of the magnetite particles have a particle size of less than 5 μm, and the magne-tite particles have a polyhedral shape and essentially isotropic magnetic properties. The magnetite particles have a saturation magnetization of 75-95 emu/g at 10 kOe, a remanence of 20-40 emu/g and a coercivity of 250-500 Oe. The invention also relates to the medium for magnetically storing information comprising magnetite particles. |
