The 2025 Joint MMM-Intermag Conference will be held at the Hyatt Regency New Orleans in New Orleans, Louisiana, USA, January 13–17, 2025. The Joint MMM-Intermag Conferences, convened every three years, are the combination of two annual premiere international conferences on magnetism: the IEEE International Magnetics Conference (Intermag) and the Conference on Magnetism and Magnetic Materials (MMM). Members of the international scientific and engineering communities interested in recent developments in fundamental and applied magnetism are invited to attend and contribute to the technical sessions. The technical program will include invited and contributed papers in oral and poster sessions, invited symposia, a tutorial, plenary, and several special sessions. This Conference provides an outstanding opportunity for worldwide participants to meet, share their research, and to discuss and learn about the most recent developments in all areas of magnetism research.
