Latest Patents

Hua Al Zeng holds a patent for a spin transfer torque (STT) device that features a free ferromagnetic layer composed of a Heusler alloy layer and a template layer beneath it. This template layer is a ferromagnetic alloy that may include elements such as Co, Ni, Fe, and others like Ta, B, Hf, Zr, W, Nb, and Mo. The design allows for the formation of a CoFe nanolayer in contact with the template layer. The STT device can function as a spin-torque oscillator (STO) or as a magnetic tunnel junction (MTJ) cell for magnetic random access memory (MRAM). Notably, the template layer reduces the critical current density of the STT device, enhancing its efficiency.
