Abstract: A magnetic isolator includes a dielectric film having a layer of electrically-conductive soft magnetic material bonded thereto. The layer of electrically-conductive soft magnetic material comprises substantially coplanar electrically-conductive soft magnetic islands separated one from another by gaps. At least some of the electrically-conductive soft magnetic islands have an outer insulating oxidized layer that electrically insulates them from adjacent electrically-conductive soft magnetic islands. The gaps at least partially suppress electrical eddy current induced within the layer of soft magnetic material when in the presence of applied external magnetic field. An electronic device including the magnetic isolator and a method of making the magnetic isolator are also disclosed.
