From 24 to 29 August 2025, researchers, innovators, and industry representatives from around the world gathered in Frankfurt, Germany, for the 14th Joint European Magnetic Symposia (JEMS 2025).

Organised by the European Magnetism Association (EMA) and supported by the Rhine-Main-Universities (RMU) alliance, JEMS is one of the largest European events dedicated to magnetic materials and their applications.

This year’s edition featured an extensive scientific programme combining plenary sessions, thematic symposia, and poster presentations, as well as special events such as the Young Researchers Network (YORNE), Diversity in Magnetism, and Industry Meets Science.

The CoCoMag consortium was strongly represented and played a prominent role throughout the week:

Prof. Oliver Gutfleisch (Technische Universität Darmstadt, CoCoMag Coordinator), chaired the conference as General Chair.

Prof. Thomas Schrefl (Universität für Weiterbildung Krems) acted as Co-Chair of the Programme Committee, contributing to shaping the scientific content of the event.

MAGNOTHERM Solutions GmbH, CoCoMag’s industrial partner, showcased its refrigerant-free magnetic cooling system, a tangible example of how cutting-edge scientific research can translate into real-world sustainable technologies.

The Universidad de Sevilla team was also actively involved, with three contributions highlighting recent advances in magnetocaloric materials:

Prof. Victorino Franco delivered a semi-plenary talk on hysteresis in magnetocaloric materials.

Dr. Jia Yan Law presented how stress relaxation can enhance the performance of magnetocaloric high-entropy alloys (HEAs).

Jorge Revuelta-Losada introduced a novel characterization technique for assessing magnetocaloric materials’ performance.

The participation of the CoCoMag partners at JEMS 2025 reflects the project’s ongoing priority to advancing magnetocaloric research and fostering collaboration between academia and industry.
