Abstract
In a magnetic bearing in which a first part is mounted magnetically relative to a second part and the second part has a Type II superconducting material containing an anisotropic crystal or a plurality of grains formed of this anisotropic crystal, this crystal being anisotropic in that the superconducting current flows in current-carrying planes, the first part has a configuration of magnets with which the superconducting material interacts, and the crystal itself or the crystal in the plurality of grains faces the first part with the normals on the current-carrying planes.

A magnetic bearing comprising:
- a first part being mounted magnetically relative to a second part;
- said second part having a Type II superconducting material containing an anisotropic crystal or a plurality of grains formed of said anisotropic crystal;
- said crystal being anisotropic in that the superconducting current flows in current-carrying planes;
- said first part having a configuration of magnets with which the superconducting material interacts;
- said crystal itself or the plurality of grains formed of said anisotropic crystal facing the first part with normals to the current-carrying planes;
- and a polygon mirror which is fastened to said first part.
A magnetic bearing comprising:
- a first part further comprising a configuration of magnets and being mounted magnetically relative to a second part;
- said second part being a Type II superconducting material which can be cooled to below its critical temperature by a connected cooling system;
- said superconducting material containing a plurality of grains, each comprising an anisotropic crystal;
- current flowing in the superconducting state flowing in every grain in a current-carrying plane of the grain;
- said superconducting material, in terms of its structure, being a melt-textured multigrain material with grain sizes in the range of 2 mm to 20 mm;
- a preferred direction of the current-carrying planes being adjusted so that an external magnetic flux direction of the magnetic flux lines of the configuration of magnets runs parallel to the normals of the current-carrying planes of the grains and a polygon mirror which is fastened to said first part.
