Title: Huanlong Liu: Innovator in Magnetic Device Technology
Introduction
Huanlong Liu is a prominent inventor based in New York, NY (US), known for his significant contributions to the field of magnetic devices. With a total of 6 patents, Liu has developed innovative technologies that enhance the functionality and efficiency of magnetic memory systems.
Latest Patents
Liu's latest patents include groundbreaking inventions such as the "Current induced spin-momentum transfer stack with dual insulating layers." This invention presents a high-speed, low-power method to control and switch the magnetization direction of a magnetic region in a magnetic device for memory cells using spin-polarized electrical current. The device comprises a pinned magnetic layer, a reference magnetic layer with a fixed magnetization direction, and a free magnetic layer with a changeable magnetization direction. By applying a current, a torque is induced that alters the magnetic state, allowing the device to function as a magnetic memory for writing information. The resistance, which depends on the magnetic state, can be measured to read out the stored information.
Another notable patent is the "Precessional magnetization reversal in a magnetic tunnel junction with a perpendicular polarizer." This magnetic device features a perpendicular magnetized polarizing layer that provides a first spin-torque, along with an in-plane magnetized free layer that has at least two stable states. The device also includes a reference layer that provides a second spin-torque. The combination of these spin-torques influences the magnetic state of the free layer, enabling the magnetization vector to oscillate between stable states when a voltage pulse is applied.
