Abstract
My project aims at an experimental study of novel phases and fundamental concepts in the field of strongly correlated electronic systems. An emphasis is put on highly frustrated antiferromagnets, a rapidly growing field, both from physics and chemistry aspects. Magnetic systems with frustrated spin lattices and with either fluctuating ground state or long-range magnetically ordered states will be inspected within the framework of the project. The research will focus on novel corner-sharing geometries, including recently discovered S = 1/2 “pure” kagome compounds and other spin systems with triangularly based and checkerboard lattices, as well as on an orthogonal-dimer compound. Novel frustrated magnetic networks, synthesized in collaborating laboratories, will also be identified, in an ultimate quest of a resonating-valence-bond spin liquid. Special stress will be put on investigating the role of magnetic anisotropy, often neglected in theory but inevitably present in real systems. I also plan to test the robustness of the ground state of frustrated spin lattices as well as their magnetic correlations and magnetic properties in general by introducing impurities into these lattices. A unique combination of bulk magnetization and heat-capacity measurements as well as local-probe electron spin resonance, nuclear magnetic resonance and muon spin relaxation experiments will be engaged in order to provide an informative experimental insight.
Significance for science
The subject and the objectives of this project represent the key objectives of the physics of highly frustrated magnetic systems, which is lately one of the major fields in the condensed matter physics. This is evident by the strong international community doing intense research in this field. The field is particularly attractive due to the immense variety of the observed physical phenomena and the application potential. Therefore, it is expected that the results of our investigation will receive great international response and will have a huge impact in the future development of this field. After all, our results have already been published in the leading international magazine devoted to physics, the Physical Review Letters.
Significance for the country
The research in the context of this project was conducted within a strong international alliance, supported by the European Science Foundation through the Highy Frustrated Magnetism project. Our research has enabled the incorporation of the Jozef Stefan Institute (and thus Slovenia) to this community of twelve European countries. This will increase the international awareness of our research and bring top-level knowledge into Slovenia.
