Dr. Anna Kosogor is a solid-state physicist specializing in magnetism and functional materials. She earned her PhD in 2012 and previously worked at the Institute of Magnetism in Kyiv (Ukraine). Her research focuses on magnetic and structural phase transitions, with particular emphasis on theoretical and phenomenological modeling of the magnetocaloric effect. She has held visiting research positions in Japan, Sweden, and Finland and has led multiple research projects funded by the National Academy of Sciences of Ukraine and international research programs. In 2025, she started an independent research project at the University of Vienna dedicated to modeling the magnetocaloric effect and linking theoretical predictions with experimental observations. Her work has been recognized by several distinctions, including the Award of the President of Ukraine for Young Scientists (2022), being a Top 10 finalist of the L’Oréal–UNESCO “For Women in Science” Ukraine Award (2021), and the Award of the Verkhovna Rada of Ukraine for Young Scientists (2016). She also supports early-career researchers and promotes the participation of women in science through her involvement in the Ukrainian Women in STEM Society.

Project: Theory of the Magnetocaloric Effect
FWF Elise Richter project RIC5537124 (“Theory of the Magnetocaloric Effect”) aims to develop a universal theoretical model of the magnetocaloric effect (MCE) to better predict and explain the cooling behavior of magnetocaloric materials. The research will derive fundamental thermodynamic relations that connect entropy, temperature change, and heat capacity with Gibbs free energy derivatives, accounting for magnetic, elastic, and electronic contributions under external stimuli such as pressure and stress. It seeks to clarify how material performance is influenced by these factors and to identify critical points in phase transition behavior. The theory will be validated and compared against experimental data in collaboration with laboratories studying magnetocaloric materials. Ultimately, the work is intended to accelerate the discovery of efficient materials for sustainable magnetic refrigeration technologies.
