Fyzikální ústav Akademie věd ČR

The department of Magnetic NanoSystems has been established in 2013 as an up-to-date successor of the Department of Magnetism and Low Temperatures. The main research topics are Magnetic nanoparticles for multimodal cancer treatment, Graphene-based nanostructures with controlled topography and synergy of enhanced Raman processes, Giant anisotropy f-electron magnets, and Fundamentals of turbulence in liquid helium. The members of the department have strong link to the Charles University in Prague through active participation in two joint research centers: Joint Laboratory of Low Temperatures and Joint Laboratory for Magnetic Studies. The department is also involved in operation of helium liquefier and management of cryogenics. The research facilities provide unique combination of extreme environments (temperatures from mK to 1000 K, magnetic fields up to 14 T and hydrostatic pressures up to 12 GPa) for studies of transport, magnetic, caloric and elastic properties of solids by variety of methods. Temperature and magnetic field induced changes of symmetry, magnetic and electronic structure, and topography are investigated using local probes: Mössbauer spectroscopy, magneto-Raman spectro-microscopy, and scanning probe microscopies.
