Title: Lujun Chen: Innovator in Spin Valve Sensor Technology
Introduction
Lujun Chen is a prominent inventor based in West Hills, California. He has made significant contributions to the field of data storage technology, particularly through his innovative work on spin valve sensors. With a total of 4 patents to his name, Chen continues to push the boundaries of what is possible in this area.
Latest Patents
One of Chen's latest patents is titled "Giant magnetoresistive sensor having self-consistent demagnetization fields." This invention focuses on a spin valve sensor designed for data storage systems. It is engineered to receive a sense current and produce a giant magnetoresistive (GMR) effect in response to applied magnetic fields. The sensor comprises first and second ferromagnetic free layers, a spacer layer positioned between them, and a biasing component. The first ferromagnetic free layer has a magnetization in a first direction, while the second layer has a magnetization in an opposing direction when in a quiescent state.
Another notable patent is the "Spin valve sensor," which is also intended for use in data storage systems. This sensor includes free and pinned ferromagnetic layers, a conducting layer in between, contact leads, and free layer biasing elements. The pinned layer defines an active region of the spin valve sensor that exhibits a giant magnetoresistive effect in response to magnetic fields. The design allows for enhanced performance in data storage applications.
