摘要: Magnetic tunnel junction cells and methods of making magnetic tunnel junction cells that include a radially protective layer extending proximate at least the ferromagnetic free layer of the cell. The radially protective layer can be specifically chosen in thickness, deposition method, material composition, and/or extent along the cell layers to enhance the effective magnetic properties of the free layer, including the effective coercivity, effective magnetic anisotropy, effective dispersion in magnetic moment, or effective spin polarization.

摘要: A device resets a biasing magnetization of a biasing element in a magnetic sensor. The device includes a magnetic structure that is magnetically coupled to the biasing element. A conductive element is disposed around at least a portion of the magnetic structure. When a current is passed through the conductive element, a magnetic field is produced that resets the biasing magnetization of the biasing element.

摘要: A transducing head includes a multilayered magnetoresistive sensor having an air bearing sidewall opposite aback sidewall and a first sidewall opposite a second sidewall. A specular layer is positioned on at least one of the air bearing sidewall, the back sidewall, the first sidewall, and the second sidewall. Each sidewall is transverse to the layers of the magnetoresistive sensor.
