Electrical dynamic testing of spintronic components at nanosecond scale (@CEA)
The European SpinTronicFactory network, created in 2016, aims to promote the search for excellence in spintronics in Europe and all the potential it holds for innovation. On August 19, 2020, it published its vision of the road map for spintronics applications in Nature Electronics and identifies the upcoming challenges:
These challenges reflect the very diverse needs of this market, which covers smart phones (3D magnetometers / digital compasses), the automotive sector (linear or angular position and speed sensors), current and power sensors, and scanners. New applications are emerging in the Internet of Things (IoT) and biomedical fields with the development of reliable low-power devices on silicon or flexible substrates.
Radio frequency and terahertz (THz) technologies
Proofs of concept have been demonstrated for oscillator and diode functions with significant potential for telecom components. They must now be integrated in different applications, including compact and low-power telecommunications, THz applications (imaging, security), micro-energy recovery and artificial intelligence.
Finally, looking further down the road, milestones are proposed to demonstrate the potential of spintronics, to directly carry out information processing using the spin of the electron and not only its electrical charge, making it possible to further reduce the consumption of electronic circuits and introduce new functionalities. The challenges identified relate in particular to the efficiency of conversions between spin current and load current in new concepts.
Meeting these various challenges will require progress in the development of non-conventional materials, the interfaces on which spintronic functionalities often depend, nanofabrication and implementation in production lines, including specific metrology. Developments will also have to be carried out in numerical simulation, ranging from the integration of new effects in multi-physical codes, to multi-scale approaches from the atom to systems.
The main objectives of SpinTronicFactory:
It is organized around four pillars of research and development:
It currently brings together 87 partners from 17 European countries (France, Germany, Italy, Spain, Poland, United Kingdom, Sweden, Turkey, Portugal, Switzerland, Netherlands, Greece, Slovakia, Belgium, Norway, Hungary, Czech Republic):
SpinTronicFactory has a close relationship with the larger European Magnetism Association (EMA), which seeks to structure the entire European magnetic community. For further information about SpinTronicFactory: http://www.spintronicfactory.eu
 The SpinTronicFactory network brings together a total of 15 French laboratories.
