Latest Patents

Frederic Holtzberg's latest patents focus on two groundbreaking technologies. The first patent, titled "Detection of magnetic domains by tunnel junctions," describes a method utilizing tunnel junctions to detect magnetic domains, such as bubble domains. The technology relies on the shift in the Fermi level of electrodes caused by the magnetic field of the domain, leading to a change in the tunneling conductance that can be measured as a current or voltage change. Although a simple tunnel junction can be effective, Holtzberg's work also explores more sensitive detectors using Schottky barrier junctions and magnetic semiconductors.

The second patent, "Information storage by laser beam initiated reactions," presents a novel and cost-effective high-density storage medium. This invention comprises adjacent thin layers of two or more materials that react when heated, resulting in a reaction product with different optical, magnetic, or electrical properties. By using reactant layers such as aluminum and selenium, the heating, notably applied through a laser beam, results in a valuable product (Al₂Se₃) that enhances data storage capabilities.
