Claims18
A magnet, comprising:
- a three-dimensional structure with nanoscale features, wherein the three-dimensional structure has a predefined shape,
- wherein the magnet is a permanent magnet with an energy product greater than 5 Mega-Gauss-Oersted to temperatures of at least 200° C.
A thin foil magnet, comprising:
- a three-dimensional structure having a predefined shape being a complex geometric shape,
- wherein the thin foil magnet comprises samarium cobalt, wherein a magnetic coercivity of the thin foil magnet at room temperature is at least 60 kiloOersteds.
A thin foil magnet, comprising:
- a three-dimensional structure with nanoscale features,
- wherein the thin foil magnet has a thickness in a range of greater than about 500 nanometers and less than about five millimeters.
