Abstract
A method of making a bulk exchange spring magnet by providing a magnetically soft material, providing a hard magnetic material, and producing a composite of said magnetically soft material and said hard magnetic material to make the bulk exchange spring magnet. The step of producing a composite of magnetically soft material and hard magnetic material is accomplished by electrophoretic deposition of the magnetically soft material and the hard magnetic material to make the bulk exchange spring magnet.
Claims20
A product comprising:
- a bulk exchange spring magnet comprising
- a first component characterized as a magnetically soft material and
- a second component characterized as a hard magnetic material,
- wherein said first component and said second component are deposited by an electrophoretic deposition process to produce a bulk exchange spring magnet that is a composite of said magnetically soft material and said hard magnetic material.
A bulk exchange spring magnet apparatus, comprising:
- a bulk exchange spring magnet body, said bulk exchange spring magnet body being a composite of
- a first component and a second component,
- wherein said first component is a magnetically soft material and
- wherein said second component is a hard magnetic material.
A method of making a bulk exchange spring magnet, comprising the steps of:
- providing a magnetically soft material,
- providing a hard magnetic material, and
- producing a composite of said magnetically soft material and said hard magnetic material to make the bulk exchange spring magnet.
A method of producing an exchange spring magnet, comprising the steps of:
- electrophoretic deposition of iron and/or cobalt and a rare earth element containing alloy to produce the exchange spring magnet.
A method of producing exchange spring magnets, comprising the steps of:
- using electrophoretic deposition of a combination of iron and a rare earth element to produce the exchange spring magnets.
