Abstract
A method of treating a preshaped magnetic material wherein a mechanical vibration and/or a high-energy beam are applied to the material held in a magnetic field.
Claims21
A method of treating a preshaped magnetic material in the manner to improve its magnetic properties, comprising:
- placing said magnetic material in an essentially unidirectional magnetic field and, imparting mechanical vibrations to said magnetic material while said magnetic material is in said magnetic field and independently of the application of the magnetic field.
A method of treating a preshaped magnetic material to improve its magnetic properties, comprising:
- placing said magnetic material in a magnetic field while imparting mechanical vibrations to said material;
- and
- applying a static pressure in superimposition upon said mechanical vibrations to said material.
A method of treating a preshaped magnetic material to improve its magnetic properties, comprising:
- placing said magnetic material in a magnetic field while imparting mechanical vibrations to said material;
- and
- applying a high-energy beam to said material while the latter is in said magnetic field.
A method of treating a preshaped magnetic material to improve its magnetic properties, comprising:
- placing said magnetic material in a magnetic field while applying a high-energy laser beam to said material.
