Abstract
Methods for altering the magnetic properties of materials and the novel materials produced by these methods. The methods concern the application of high voltage, high frequency sparks to the surface of materials in order to alter the magnetic properties of the materials. Specificaly this method can be applied to diamagnetic silicon to produce ferromagnetic spark-processed silicon.
