| 摘要 |
The process involves application in layers of a pourable anisotropic material in a soln. of a polymer binding agent, and additives in an organic solvent, onto a non-magnetic carrier material. The magnetic anisotropic particles are aligned in the dispersion layer in a preferred direction, which is also to the plane of the carrier material. The coating is fastened and dried. Directly before application onto the carrier material, the dispersion is subjected to a penetrating magnetic field. The homogenous magnetic field has a field strength, which is higher or of the same size as the coercive field strength of the magnetic material used. |
