Magnetic nanostructures

Head of the Division:

Assoc. Prof. Jiří Tuček, PhD

Jiří Tuček received his PhD. in Applied Physics at the Palacky University in Olomouc, Czech Republic, in 2008. In 2013, he became an Associate Professor at the Department of Experimental Physics at the Faculty of Science of the Palacky University. He is currently a Senior Researcher at the Regional Centre of Advanced Technologies and Materials, Palacky University in Olomouc, Czech Republic. In 2015, he was appointed as a part-time lecturer at the Graduate School of Science, The University in Tokyo. He is the author or co-author of more than 90 publications, author of one chapter in the book, and co-editor of processings from the international colloquium on “Mössbauer Spectroscopy in Materials Science”. His research interests include magnetism in the nanoworld, particularly the magnetic behavior and properties of iron-containing compounds such as iron and iron oxide nanosystems, 57Fe Mössbauer spectroscopy, and carbon nanostructures.


Research Areas

The group focuses on study of magnetic properties of various nanostructured materials based on iron, nonhydrated iron oxides and carbon and their hybrids including also molecular complexes. A significant attention is devoted to understand the mechanisms driving the materials’ magnetic features, describe the magnetic behavior in the nanoworld and identify parameters that can tune the magnetic properties to enhance the materials’ applicability. The applicability of such nanostructures spans from technological, biomedical to environmental fields in which they are tested. For a magnetic characterization, a broad portfolio of experimental techniques are employed including Mössbauer spectroscopy in various modes (low-, room-, and high-temperature, in-field, in-situ, etc.) magnetometers (SQUID, PPMS device), and EPR. Besides, the group disposes of instruments for TG and DSC analyses. The group activities also involve simulation and theoretical studies constructing models to describe the magnetic properties of, particularly, carbon nanostructures. Besides research, the group participates in development and construction of Mössbauer spectrometers that are sold worldwide.
