Professor
Björgvin Hjörvarsson is a Professor in Physics at Uppsala University's Department of Physics and Astronomy, specifically within the Materials Physics division where he served as Head until 2024. He is Principal Investigator of the Super ADAM project, Sweden's national neutron facility, and an elected member of both the Royal Academy of Sciences and the Royal Society of Sciences in Uppsala. His research spans low-dimensional aspects of phase transitions, particularly in magnetism and hydrogen in metals. His work has evolved to emphasize finite size effects on structural and magnetic ordering, additive manufacturing, and energy storage and transformation. His research methodology heavily relies on neutron scattering techniques and international collaborations across experimental and theoretical physics. Hjörvarsson's recent publications (2022-2025) reveal a strong focus on metallic glasses produced via additive manufacturing, artificial spin ice systems, magnetic superlattices, and advanced characterization techniques. His work bridges fundamental physics with practical applications in energy storage, materials engineering, and biomedical technologies. Vattenfalls Energistipendium (1985) Liljewalchs scholarship (1989) Good-Guy Award from Fysiska Sällskapet (1990) Idée award from Uppsala University (1995) Benzelius award from Royal Society of Sciences of Uppsala (1995) Letterstedtska award from Royal Swedish Academy of Sciences (2003) Hjörvarsson has supervised 27 PhD students to completion, 1 licenciate student, and currently guides 9 PhD students while supervising 2-3 master's students annually. His research is supported by significant infrastructure including the Super ADAM neutron facility at ILL, Grenoble, which he initiated and developed as Sweden's national neutron scattering infrastructure. Beyond traditional research, he's known for innovative outreach efforts including educational videos on neutron science. Hjörvarsson leads the Materials Physics research group, which maintains strong international collaborations and focuses on experimental condensed matter physics with connections to engineering applications. His team operates specialized laboratories for thin film growth, magnetic characterization, and neutron scattering experiments, supporting both fundamental research and industrial applications.
