Abstract

The pattern consists of a magnetic material containing the material forming the substrate, and one or several other materials which are implanted by a focused, deflectable ion beam to form a desired pattern. The magnetic material is at least partly embedded in the substrate (see Figs. 1 and 2).

Pattern Consisting of a Magnetic Material and Method of Producing the Pattern

The pattern consists of a magnetic material containing the material forming the substrate, and one or several other materials which are implanted by a focused, deflectable ion beam to form a desired pattern. The magnetic material is at least partly embedded in the substrate (see Figs. 1 and 2).

The pattern can consist of concentric, discrete traces on a magnetic disk, whereas the magnetic material can be a Heusler alloy, such as Mn, Cu, Al, with Al being the substrate material.

The method of ion implantation allows ions to be implanted within the pattern, either at a highly homogeneous layer thickness or at a layer thickness varying in a controlled manner. With magnetic disks, for example, it may be advantageous to increase the thickness of the implanted layer as the proximity to the center increases.
