Roberto ZYSLER

Researcher CONICET

Expertise: Nanostructured materials: synthesis of the magnetic nanoparticles (usually by chemical route), the morphological characterization, and the magnetic property research, mainly the magnetic order, the effective magnetic anisotropy and the superparamagnetic relaxation of the magnetic moment of the nanoparticles (DC Magnetization, AC Susceptibility, Mössbauer spectroscopy and Ferromagnetic Resonance). The experimental results are describing with theoretical models or simulating by Monte Carlo method. Applications of magnetic nanoparticles in biology and medicine: diagnostic & treatment (MRI contrast, hyperthermia, drug delivery, ophthalmologic treatments, etc.) 2005-present.
