Summary on Grant Application Form |
|
Magnetic sensor Technology is a strongly growing industry, which has been satisfied in some areas by MR and GMR and other Technologies. Giant Magneto-impedance (GMI) is a candidate to equal or even take over some of these emergent sensor systems in terms of performance and lower cost (published works by applicants and other groups have reported 30-100 %/OE change in amorphous wires and multilayers). This project seeks to advance GMI sensors by investigating thin-film systems with asymmetric characteristics, which produce a linear response in the nano-Tesla region, Not requiring Large amounts of power consumption. We propose o use magnetic/metallic sandwich structures with crossed magnetisation. This will be investigated both theoretically (via a new two-dimensional algorithm approach) and experimentally (by fabricating a range of candidate structures and their testing). Measurements of asymmetrical GMI characteristics will be made via S21 parameter at high frequency (>100Mz) for different DC & ACBais. Pulse-Biasing characteristics will also be investigated using suitable electronic circuits, which is important for designing practical sensor elements.
