Patents by Inventor Jiexuan He

Jiexuan He has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Partial magnetic biasing of magnetoresistive sensor
    Patent number: 9041391
    Abstract: Various embodiments can be generally directed to a magnetoresistive stack with a first stripe height and a biasing magnet positioned adjacent the magnetoresistive stack. The biasing magnet can have a second stripe height that is less than the first stripe height. The first and second stripe heights may correspond to a minimum signal to noise ratio in the magnetoresistive stack.
    Type: Grant

    Date of Patent: May 26, 2015
    Assignee: Seagate Technology LLC
    Inventors: Kaizhong Gao, Jiexuan He, Jiaoming Qiu
  • Magnetic element with increased scissoring angle
    Patent number: 8582247
    Abstract: An apparatus and associated method is presently disclosed for a data sensing element capable of detecting changes in magnetic states. Various embodiments of the present invention are generally directed to a magnetically responsive lamination that has a spacer layer disposed between a first and second ferromagnetic free layer. The lamination having at least one free layer with a shape feature that increases a scissoring angle between the free layers.
