Methods for altering the magnetic properties of materials and the materials produced by these methods

摘要

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