Magnetic lithographed nanostructures are at the heart of most spintronic devices (e.g., magnetic random access – MRAM or sensors). Similarly, magnetic nanoparticles have demonstrated a potential in a broad range of disciplines, from medical applications to magnetic recording. At the same time, these types of systems exhibit a variety of novel properties which have not been exploited in applications.
The research carried out at the Magnetic Nanostructures group is focused toward the basic understanding of different types of magnetic nanostructures with the aim of improving their functional properties. We combine state of the art lithographic or chemical synthesis methods with structural, morphological and magnetic characterization.
The different research topics of the group can be divided in:
-
* Magnetic Properteis of Lithographed magnetic nanostructures:
- Morphological effects
- Interface exchange coupling
- Novel nanofabrication methods
- Novel materials
- Sore-shell nanoparticles
* Magnetic nanoparticles
* Other, non-nanometric, systems
(a) Atomic force microscopy (AFM) and magnetic force microscopy (MFM) images at different fields and
(b) Magneto-optic Kerr effect (MOKE) hysteresis loop of 400 nm diamter dots of IrMn/FeNi. The data confirms the existence of a displaced vortex.
