電壓操控奈米磁性元件的新穎機制研發：利用電場引導氫化磁性材料的磁矩轉向(2/2)

This project proposes to control the magnetic properties of the material by controlling the movement of hydrogen ions in magnetic metal materials through electric field control, with the ultimate goal of reading and writing magnetic recording elements. This idea requires overcoming multiple challenges from the physical mechanism and material selection, such as the source of H atoms, the control mechanism of H atoms, the diffusion rate of H atoms, and the reaction time. Our team expects to use Mg alloy as the hydrogen storage material, and pre-select Pd-related vertical magnetic alloy films to apply voltage through the upper and lower electrodes, creating a local electric field to drive the hydrogen re-diffusion distribution in the hydrogen storage material. This two-year project is divided into the following three stages: (1) hydrogen storage material growth and basic testing, (2) preliminary component preparation and testing, and (3) advanced component preparation and testing. The three PIs have different expertises and play important research and development roles. Lin’s team: hydrogen storage materials and magnetic reactions, Lo’s team: oxide layer encapsulation and electrode structure preparation, Hong’s team: tunneling magnetoresistive element production and testing. Our team has accumulated many years of experience and energy in the field of related hydrogenated magnetic materials and magnetic components. We are confident that we can develop this novel magnet control mechanism and integrate it into magnetic components. We also hope to contribute to Taiwan's related technology industries.
