Abstract

See full text

The invention relates to the identification of molecules using electromagnetic write-heads and magneto-resistive sensors. In one embodiment, an electromagnetic write-head magnetically excites a molecule with an alternating magnetic field. A magneto-resistive sensor measures the resonant response of the magnetically excited molecule. A processor compares the resonant response to a table of known responses of different molecules to identify the chemical composition of the molecule based in whole or in part on the comparison.
