Summary on Grant Application Form |

The proposal is aimed to investigate a new type of giant magneto-impedance (GMI) effect in thin amorphous wires and films, characterised by an asymmetrical behaviour with respect to the sensed magnetic field (AGMI). Owing to its extremely high sensitivity (up to 100%/Oe at 1MHz for Co-based amorphous wire), the GMI element can be a candidate for next generation magnetic sensors in low-field magnetic sensing applications. However, the strong non-linearity of fundamental GMI characteristics can be realised in a magnetic wire with induced helical magnetisation subjected to the combination of ac and dc currents. Wire samples will be provided by our collaborators from Madrid University. Using the analogy with AGMI in a wire, the effect will be modelled for thin film geometry, which is especially important for development of AGMI integrated circuit sensors. The film element will consist of two ferromagnetic layers with in-plane crossed anisotropy, sandwiching a non-magnetic conductive lead. Finally, the overall aim is to apply AGMI in layered films to the creation of a prototype of a linear miniature magnetic sensor.
