Abstract
A magnetically shielded conductor assembly with a conductor device and a film of nanomagnetic material located above the conductor device. The conductor device has a resistivity of from about 1 to about 2,000 micro ohm-centimeters. The film of nanomagnetic material has a thickness of from about 100 nanometers to about 10 micrometers and a magnetic shielding factor of at least about 0.5. The nanomagnetic material has a mass density of at least about 0.01 grams per cubic centimeter, 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.
