The rapid development of our digital world is creating strong demand for magnetic sensing. The aim of the ADAGE Targeted Project is to develop more sensitive, energy-efficient, agile and versatile sensors by combining an in-depth understanding of nanomagnetism, improved nanofabrication, new materials and electronic architectures for a new generation of spintronic sensors with enhanced functionality.

Challenges

>Increase signal-to-noise ratio

>Develop sensors with adjustable properties

>Develop intelligent sensors capable of adapting their configuration at runtime to optimize detection

>Develop front-end electronics and signal processing

Implemented solutions

>Develop devices incorporating innovative concepts and/or architectures, possibly based on well-mastered building blocks, using a detailed understanding of nanomagnetism and transport.

>Improving nanofabrication, new materials and new electronic architectures.

More precisions

To this end, a number of scientific and/or technical challenges will have to be met within the framework of ADAGE. Firstly, the signal-to-noise ratio (SNR) will be improved, aiming for a gain of at least a decade compared with the current state of the art. Secondly, a new generation of intelligent sensors with adjustable properties (range, linearity and directivity) will be developed, capable of covering various applications or adapting their configuration during operation.

To this end, a combination of magnetic simulations, specific electronics, new materials and stack architectures, incorporation of high-performance concentrators, coupling with acoustic waves and incorporation of spin torque effects, will be used to control the properties of the various magnetic layers.
