The next generation of sensing tools are expected to deliver top performance for high precision detection, whilst having tuneable properties, being ultracompact and multifunctional, and provide seamless integration in hybrid platforms. Magnetoresistive sensors can fulfil the requirements of high sensitivity and spatial resolution in magnetic field detection, ideal to leverage applications. Still, their operation parameters are set to fit (usually narrow) final requirements. These are defined and imprinted during thin-film deposition and fabrication. Being able to manipulate, as needed and during operation, the sensing device properties has the potential to push further the limits of performance, broaden applications of spintronic sensors, or possibly extend their lifetime. Critical challenges involve the design of variable linear sensing range or customized temperature windows for magnetic field detection.
This project will explore pathways to adjust sensor field sensitivity, on demand, allowing to correct for changes in distance from magnetic field sources, or field intensity over time. Such capabilities will allow the design of versatile devices, suitable for tuneable biomedical and position sensors.
The work will be carried out in the group Physics of Nanostructures (FNA) at the department of Applied Physics of the Eindhoven University of Technology (TU/e) where you will be part of a research team developing hybrid magnetic sensors. This environment enables you to work in close collaboration with other colleagues fostering creativity and leadership, and providing a strong basis for the success of your project.
This work aims at delivering new solutions for magnetoresistive sensors design demonstrating a variable linear operation range. Strategies based on materials engineering are a promising route as they provide a solid route to ensure compatibility with current thin-film stacks and patterning processes. Using the available state of the art facilities at TU/e for thin film deposition, nano/micro fabrication, and characterization, your research will target novel schemes to manipulate effectively the magnetic properties of the sensing layer. The initial approach will consider layered ferrimagnets near the compensation temperature (e.g. Co/Gd systems), whose changes in the magnetic behaviour can be driven by spin orbit torques and/or local temperature changes. This can be expanded further to include different thin-film materials and stimuli. In addition, engineering of the magnetoresistive multilayers by creating compositional variations has been successfully used for memory applications, and can provide a wide playground for the desired tunability in sensing devices. Such tailor made changes have a direct impact on sensors properties and performance.
