MagNano – Magnetic Nanosystems
The main goal of the
Magnetic Nanosystems Group
is to apply its accumulated know-how on atomic and magnetic systems, nanophysics and nanotechnology methods and use/development of high resolution experimental techniques to tackle relevant issues for innovative applications in biology & environmental sciences, in collaboration with other BioISI groups, while continuing to develop its own expertise.
The MagNano group is comprised of 14 PhD physicists, with a research focus on the study of magnetic, electrical and optical properties of nanostructured systems targeting the design of new materials with different functionalities and practical applications.
The group is organized along the 3 research teams: ‘Magnetic systems’, ‘Electronic structure calculations’ and ‘Atomic force microscopy related techniques’ that bring together the major research approaches developed (experimental studies on magnetic systems, electronic structure calculations, and atomic force microscopy related techniques development and applications).
The MagNano research activity has a strong experimental basis, relying crucially on the preparation of high quality systems and on the assessment of their physical properties using high resolution techniques. It is supported by various in house high resolution experimental techniques (SQUID magnetometry, magneto-transport measurements, Mössbauer spectroscopy, magneto-optic Kerr effect, Atomic Force and Force Feedback Microscopy) together with other facilities available through the established collaborations.
Specific lines of research in BioISI include: 1) optimization of magnetic nanoparticles (MNP) for biological/biomedical applications; 2) Development of Force Feedback Microscope (FFM) studies in biological systems; 3) Study of 3d magnetic centre complexes with thermal spin transitions & spin crossover transition metal complexes with potential applications in catalysis, nanomedicine & sensors technology; and 4) Development/study of films and heterostructures based on Fe & Co oxides/nitrides and artificial multiferroics assembling ferromagnetic/ferroelectric materials, to accomplish integration in magnetic tunnel junctions and biosensors
The contribution of MagNano within BioISI strategic project is assembled in the Condensed Matter & Biological Physics thematic line (TL) strong interactions with the Biomedicine, and Biotechnology & Biofoods TLs.
