Latest Patents

Dong Young Kim holds a patent for a magnetic sensor that includes a magnetic layer of a closed loop shape. This innovative sensor is designed to detect magnetic fields effectively. It features a pair of current terminals that face each other and contact the closed loop, allowing for current input and output. Additionally, it has a pair of voltage terminals that also contact the closed loop, from which the output voltage is detected. The sensor utilizes both an anisotropic magnetoresistance effect (AME) and a planar Hall effect (PHE) to contribute to the output voltage. Notably, the design eliminates hysteresis in the output voltage through the exchange coupling of a ferromagnetic layer with a ferromagnetic-antiferromagnetic layer structure and a ferromagnetic-metal-antiferromagnetic layer structure. This advancement minimizes hysteresis due to the demagnetization factor of the closed loop, stabilizes the output voltage, and enhances sensitivity.
