A shielded medical device implanted in a biological organism. The device has a magnetic shield, and the magnetic shield contains a layer of nanomagnetic material; such layer has a morphological density of at least 98 percent; and it is bonded to the medical device by means of an interlayer with a thickness of less than about 10 microns. The nanomagnetic material in such layer has a saturation magnetization of from about 1 to about 36,000 Gauss, a coercive force of from about 0.01 to about 5,000 Oersteds, a relative magnetic permeability of from about 1 to about 500,000, and an average particle size of less than about 100 nanometers.

The nanomagnetic material in such layer has a saturation magnetization of from about 1 to about 36,000 Gauss, a coercive force of from about 0.01 to about 5,000 Oersteds, a a relative magnetic permeability of from about 1 to about 500,000, and an average particle size of less than about 100 nanometers.

A magnetically shielded substrate assembly includes a substrate and, disposed over the substrate, a magnetic shield with a magnetic shielding factor of at least about 0.5. The magnetic shield has a film of nanomagnetic material containing at least about 40 weight percent of nomagnetic material with a mass density of at least about 0.01 grams per cubic centimeter, a saturization magnetization of from about 1 to about 36,000 Gauss, a coercive force of from about 0.01 to about 5,000 Oersteds, a relative magnetic permeability of from about 1 to about 500,000, and an average particle size of less than about 100 nanometers. This film of nanomagnetic material has a squareness of from about 0.5 to about 1.0.
