Latest Patents

Duane C Phinney holds a patent for a "Wafer level test structure for detecting multiple domains and magnetic." This invention provides a method for detecting multiple magnetic domains and magnetic domain instability in a test magnetic element. The apparatus includes a first MR sensor designed to maintain a single magnetic domain by shape anisotropy and a second MR sensor equipped with a permanent magnet to achieve the same. A circuit connects these sensors to detect resistance changes in the presence of a magnetic field, indicating the presence of multiple magnetic domains. The stability of magnetic domains can be tested by applying an external field to disrupt the existing single domain state and observing resistance differences during the reversal of the magnetic field.
