GIANT teams have for many years been recognized internationally for their expertise in magnetism. More recently, Grenoble has also become a major site for spintronics. This development is the result of a concerted effort to create the tools for producing and characterizing magnetic nanostructures, in cooperation with the existing local network of large-scale European research facilities.
Work in nanomagnetism and spintronics by GIANT members spans a wide range of activities, from fundamental research to applications via the creation of functional demonstrators. The community is highly structured with a large degree of interaction between the laboratories, resulting in several collaborative projects and a large number of joint publications.
GIANT nanomagnetism and spintronics research activities include:
- Theory of magnetism and magnetic transport
- Magnetism of nano-objects (nanoparticles, domain walls)
- New functional materials
- Spintronics in nanopillars and unique objects
- Imaging (Kerr, Lorentz microscopy, MFM, PEEM, etc.)
- Numerical simulation and modelling
- Physics of complex media and biological objects
- Spin transfer and RF components
- Physics of magnetic components.
- Spin electronics are involved in the creation of a new electronics paradigm, resulting in very low energy dissipation and frequencies. Researchers in Grenoble work closely with industrial partners to determine how these new concepts can be used in future applications.
- Understanding and controlling magnetization dynamics on sub-nanosecond and sub-nanometer scales.
- Understanding and controlling spin currents and imagining new functions.
- Extending spin-dependent transport to ultimate nanostructures by combining transport and optical or microwave spectroscopy / handling.
- Optimizing the fusion of CMOS and magnetic technologies.
- Developing magnetic imaging techniques, including studies on wall movements using polarized currents, based on expertise in magnetic imaging acquired and developed by the three GIANT laboratories and developed with local large-scale European research facilities.
- Developing simulation and modeling techniques to improve the understanding of local interaction between electron spin and transport and of the effects of electron spin on local magnetization.
GIANT nanofabrication platforms are available to make samples at increasingly smaller dimensions, as required for advanced work in nanomagnetism and spintronics.
