Patent ID: 7625633

Claim:
An electromagnetic noise suppressor having: a base material containing a binding agent, the base material comprising a surface; and a composite layer consisting of the binding agent that is a part of the base material and a magnetic material integrated with each other and consisting of a crystal portion made of nanometer scale crystals of atoms of the magnetic material disposed at a spacing of several angstroms in a crystal lattice, a binding agent portion including the binding agent without the nanometer scale crystals of the atoms of the magnetic material, and a dispersed portion wherein atoms of the magnetic material are dispersed without crystallizing in the binding agent; the composite layer formed by an application of the magnetic material to the surface of the base material by physical vapor deposition with particle energy in a range from 5 eV to 1000 eV, wherein surface resistivity of the composite layer is in a range from 1×10 1 to 1×10 10 Ω/□; and the composite layer has a thickness in a range from 0.005 μm to 0.3 μm.
