    摘要： A method and apparatus for detecting the presence of magnetic beads is disclosed. By providing both a static magnetic field and a magnetic field that alternates in the MHz range, or beyond, the bead can be excited into FMR (ferromagnetic resonance). The appearance of the latter is then detected by a magneto-resistive type of sensor. This approach offers several advantages over prior art methods in which the magnetic moment of the bead is detected directly.

    摘要： A MRAM structure is described that has a dedicated data storage layer formed between first and second electrodes and a dedicated data sensing layer between second and third electrodes to enable separate read and write functions. A diode between the storage layer and first electrode allows a heating current to flow between first and second electrodes to switch the data storage layer while a field is applied. A second diode between the sensing layer and third electrode enables a sensing current to flow only between second and third electrodes during a read process. Data storage and sensing layers and the three electrodes may be arranged in a vertical stack or the sensing layer, second diode, and third electrode may be shifted between adjacent stacks each containing first and second electrodes, a storage layer, and first diode. Second electrode and the sensing layer may be continuous elements through multiple MRAMs.

    摘要： A track shield structure is disclosed that enables higher track density to be achieved in a patterned track medium without increasing adjacent track erasure and side reading. This is accomplished by placing a soft magnetic shielding structure in the space that is present between the tracks in the patterned medium. A process for manufacturing the added shielding structure is also described.

    摘要： Detection of magnetic beads at temperature below room temperature can increase the signal level significantly as compared to the same detection when performed at room temperature. Additional improvement is obtained if the beads are below 30 nm in size and if deviations of bead size from the median are small. A preferred format for the beads is a suspension of super-paramagnetic particles in a non-magnetic medium.
