Publication number: 20140342463Abstract: In general, the present disclosure is directed toward a novel hybrid spintronic device for converting chemical absorption into a change in magnetoresistance. This device uses a novel magnetic material which depends on the attachment of an organic structure to a metallic film for its magnetism. Changes in the chemical environment lead to absorption on the surface of this organometallic bilayer and thus modify its magnetic properties. The change in magnetic properties, in turn, leads to a change in the resistance of a magnetoresistive structure or a spin transistor structure, allowing a standard electrical detection of the chemical change in the sensor surface.Type: ApplicationFiled: January 2, 2013Publication date: November 20, 2014Applicant: UNIVERSITY OF SOUTH CAROLINAInventor: UNIVERSITY OF SOUTH CAROLINA
