Magnetic structure suitable for the propagation of single-walled magnetic domains |
摘要 |
A magnetic structure in which magnetic domains can propagate. The structure comprises a monocrystalline gallium garnet substrate having a surface which is substantially parallel to a (100) crystal plane and on which a layer of rare-earth iron garnet, having a partial substitution of maganese ions in iron sites, is grown in compression. By using a substrate material having a lattice constant between 12.23 and 12.38 ANGSTROM , the compression of a epilayer having certain desired magnetic properties can be adjusted by adjusting the incorporation of lutetium and yttrium ions in the epilayer, without adversely affecting magnetic properties of the layer.
